The First Amendment protects you from the government. Facebook censoring you is not prohibited by the First Amendment. More broadly, I don’t see how GDPR interferes with one’s right to lawful political speech.
It says nothing in the text of the first amendment that direct threats of violence are not covered. If that restriction is compatible with the first amendment I don't see why a future right to be forgotten can't be.
Blockchains storing social data is good example. It's infringing by nature GDPR. A decentralised facebook-like social network on the blockchain is not possible anymore. Each node can be sue. It had happened with TOR exit nodes.
IANAL, but crypto-shredding seems to be a viable way to meet GDPR deletion requirements, making it possible to implement compliant blockchains. Of course you'd have to make the nodes comply, but that has nothing to do with blockchains.
But I still don't see the connection with the first amendment.
Yes, protects, it doesn't require them to. Facebook and its likes volunteering to destroy personal data on request really doesn't have anything to do with the first amendment at all.
Edit: come to think of it I'm not even sure it protects them, but again, it certainly doesn't require them to store or transmit anything.
If you want to run a social media platform, GDPR is infringing your freemdom of speech. You can argue that it’s worth it, for the illusion of more privacy. I just don’t think it is.
If on your social network someone wants his posts to be removed, you have to comply under GDPR, or else. HN for example doesn’t allow to remove your comments after some time.
If it's a part of conversation - like most of social media posts -, I would assume it's fair use to keep it. Like if I interview you, and I publish the video, you can't retract what you said. Why social medias should be different?
