@Xantulon @doot Put it this way - if Meta Platforms Inc/Twitter Inc/Alphabet Inc holds data about you that you don't want it to, and you are in a jurisdiction subject to GDPR or equivalent, they are an identifiable legal entity, you can sue them, and they will have an actual legal team and an actual data protection officer.
Something out on Fedi you want deleted? Have fun suing the hundreds of random - possibly anonymous - Fedi admins in numerous different countries that hold copies of it!
