I wouldn’t assume the EU would necessarily be interested in protecting the Fediverse. Legislation like the GDPR is very much oriented towards working with corporate entities and the open Fediverse model is generally at odds with the right to be forgotten (since it’s effectively impossible to ensure all copies of a user’s data are deleted - I don’t even think it’s possible to determine which nodes may have a copy of a year old post).
I too am a happy customer. The ability to tweak individual site ranking especially makes searching the internet so useful again.
