Then show me the handful of European, medium-sized companies competing for customers. The problem is that you pass DMA, DSA, GDPR, etc. which Google, Apple etc. can fight for years in court and if they have to pay a few billion, so be it.
Instead what's happening is that European alternatives (the kind that's actually good, not the kind that's European and half as good) don't exist and the incentives to build one shrink because any scaling company is instantly hamstrung.
