The EU appeal the article is about has nothing at all to do with GDPR, user data, or privacy.

It's about anticompetitive behaviour, i.e. antitrust. Antitrust is not particularly about tech companies, and it has been around a long time, since before modern computers.

It's about misusing a position of market dominance to prevent a healthy competitive market from operating. Very large companies which are market-dominant face this problem, but they also have the resources to understand and handle the responsibility. They can either do so, or face fines and injunctions to make them do so. In severe cases they can be forced to break up dominant business units, such as happened with the breakup of AT&T in the USA some years ago.

This is the same sort of thing as might have blocked nVidia from buying ARM, for example (until nVidia pulled out voluntarily). You can see how that has nothing to do with GDPR; it wasn't even in the EU.
