So…

Some troll put together a fake ad, put it on a ad-sharing site saying someone was a prostitute, and the site took down the ad about an hour after the someone complained. But in that hour some other trolls copied the ad elsewhere, and so the someone sued saying the ad-sharing site should have stopped the other trolls.

The upset someone sued in file-sharing site in Romania, and rather than getting laughed out of court like a NFT dork complaining about right-clicking they got a favorable ruling, and now both halves of the fediverse are unlawful in the EU.

This is just FUD. The ruling has nothing to do with federation, and there is no reason why GDPR would prevent content sharing when the user has explicitly agreed to their posts being shared with other servers.
