The EU's anti-trust case against Google doesn't even try to alter Google's collection of so much data about people.

Existing anti-trust law, by focusing on whether companies engage in unfair competition, fails to protect the public interest. Even if a company gets big only by "doing a good job", the resulting situation enables it to engage in various abuses, and by that point it may be too late to arrange for it to have competitors again.

Beyond that, the sheer size of companies makes it had for businesses to regulate them, and that is dangerous in itself. We need to go beyond laws to protect competition and start preventing companies from getting too big.
