I've seen the debate and some politician said that big platforms should be stopped. Which is why I thought that why not work on creating an environment that supports competition rise from the EU? But yeah, it shouldn't matter where new players come from, however I think a Chinese startup will laugh at GDPR and upload filters.
This is ends up being effectively a tariff, though - if fewer advertising platforms can take European customers, then that allows those platforms to raise their prices for those customers, essentially meaning that European businesses end up paying more for advertising than their competitors from elsewhere.
