tl;dr : The EU must safeguard under all circumstances the privacy of EU citizens and should do so actively.
" However, as regards that person’s registration for the ‘GoGreen’ event, the General Court finds that, by means of the ‘Sign in with Facebook’ hyperlink displayed on the EU Login webpage, the Commission created the conditions for the transmission of his IP address to Facebook. That IP address constitutes personal data which, by means of that hyperlink, were transmitted to Meta Platforms, an undertaking established in the United States. That transfer must
be imputed to the Commission.
At the time of that transfer, on 30 March 2022, there was no Commission decision finding that the United States
ensured an adequate level of protection for the personal data of EU citizens. Furthermore, the Commission has neither demonstrated nor claimed that there was an appropriate safeguard, in particular a standard data protection clause or contractual clause. 5 The displaying of the ‘Sign in with Facebook’ hyperlink on the EU Login website was entirely governed by the general terms and conditions of the Facebook platform.
The Commission did not, therefore, comply with the conditions set by EU law for the transfer by an EU institution,body, office or agency of personal data to a third country.
You understand that lemmy is also in violation, yes?
Do you mean below mentioned issue?
Lemmy@World instance servers are in the EU. I think in The Netherlands, so they must comply. On the otherhand it's federated, so messages are copied. Lemmy isn't as big a platform as Meta, so the rules are less strict, iirc.
As far as I understand it, with federation only your username and the content of your posts and comments is transferred to other instances, which is not personal identifiable information
