I disagree. I think Facebook, X, TikTok and the rest have a vested interest in NOT keeping your data private. In fact, I think their entire business model is predicated on selling ingormation about people, which is the opposite of protecting it.
Some nostr relays undoubtedly do the same, but with corporate social media abuse of personal information is guaranteed.
I think we can all agree that people should use Tor or a VPN or some kind of proxy no matter what they do online, be it shopping, posting cat pictures, or engaging in civic discourse.
