TikTok’s fight with the European Union has moved from regulators’ desks to the bloc’s highest court, and the stakes reach far beyond Brussels. The company is arguing that it should not carry the EU’s “gatekeeper” label under the Digital Markets Act, the rulebook built to curb the power of major digital platforms and open room for rivals.
For ordinary users, that legal jargon can sound distant. It is not. The result could shape how apps recommend videos, how much control people have over their data, how easily services talk to each other, and whether future platform rules spread well beyond Europe.
Why TikTok is in court
The DMA was written to stop a handful of huge platforms from acting like digital toll booths. Under the law, companies can be tagged as gatekeepers when they run core services, have massive user bases, and hold a durable market position. The standards are high enough to catch firms that have become hard to avoid in everyday online life.
TikTok, owned by ByteDance, says the label is being applied too broadly in its case. The company has taken issue with the EU’s view that its social platform and TikTok for Business fit the gatekeeper definition. It is challenging that decision in Europe’s top court after earlier efforts to overturn the designation failed.
That matters because the gatekeeper label is not symbolic. Once a platform lands on that list, it must follow a strict set of obligations meant to limit self-preference, improve interoperability, and reduce lock-in. In practice, that can force changes in how an app ranks content, shares data, and connects with third-party services.
What the DMA asks of big platforms
The Digital Markets Act is one of the EU’s most ambitious attempts to rein in platform dominance. It covers services such as social networks, app stores, search engines, messaging tools, and other online gateways that millions of people use daily. The EU currently treats 22 core platform services from six companies, including Alphabet, Amazon, Apple, ByteDance, Meta, and Microsoft, as falling under the regime.
The rules are unusually concrete. Gatekeepers may have to allow third-party services to interoperate with their own. They can be required to give business users more access to performance data. They are barred from pushing their own products ahead of competitors’ in unfair ways. Users must also be able to remove pre-installed software more easily, and tracking outside the core service requires clear consent.
The penalties are severe enough to keep executives awake. A company that breaks the rules can face fines worth as much as 10% of global annual turnover, rising to 20% for repeat breaches.
For TikTok, the problem is not only the fines. DMA compliance could reshape how its recommendation system works, how it sells advertising, and how it shares signals with creators and brands. Those parts of the product sit close to the heart of the app’s appeal.
The broader legal stakes
The case now sits before the General Court of the European Union, with the chance of further appeal to the Court of Justice itself. That gives the dispute a legal reach that extends beyond one app and one regulation.
If TikTok wins, the company would avoid the DMA’s toughest obligations for now. That would preserve the current structure of the app in Europe, including its data model, its business tools, and its recommendation engine. Users would likely see little immediate change in the way the platform behaves.
If TikTok loses, the company would have to make deeper adjustments. That could mean more data portability for users, more openness for outside services, stronger transparency for advertisers, and potential changes to the way TikTok surfaces its own tools and features. For a company built on fast, highly personalised engagement, those are not minor edits.
The case also tests how far the EU is willing to go in defining platform power. Social media apps are not traditional infrastructure, yet they now function as gateways for attention, commerce, and discovery. If the court backs the Commission, it would signal that reach and dependence alone can be enough to trigger serious competition oversight.
Why South African users should care
The direct legal fight is European, but the ripple effects can travel quickly. Big platforms often avoid running multiple versions of the same product if the changes required in one large market are easier to spread globally. That is how European rules on privacy and consumer protection have often ended up influencing apps far outside Europe.
If TikTok has to support stronger data portability, clearer consent flows, or more transparent business tools in the EU, some of those features could be offered to users elsewhere too. South Africans might then see more control over account data, easier migration between services, or clearer explanations of how their information is used.
There is also a competition angle. South Africa’s own digital market is shaped by global platforms with enormous scale. A strong EU win could encourage local regulators to think harder about whether dominant apps need special rules to keep markets open to smaller players. That would matter for local startups trying to compete for creators, advertisers, and everyday users.
POPIA already sets baseline privacy expectations in South Africa. A wider global shift toward DMA-style rules could push platforms to build privacy and choice into their products by default, rather than treating those features as regional exceptions.
A case with reach far beyond Europe
TikTok’s challenge is about more than a label. It is a test of whether a platform that dominates attention on a global scale can argue that it should be treated like a normal app rather than a regulated gatekeeper. The answer will help define how much control big platforms keep over their ecosystems, and how much power regulators have to break those ecosystems open.
For consumers, the outcome could influence what apps look like in the next few years, not just in Europe but in markets like South Africa too. The courtroom fight is happening in Luxembourg. The product changes could end up on phones everywhere.
