I can't see community-hosting taking off. I do not trust anybody telling me about E2E encryption that I can not prove.

I barely trust Google.

I trust the long bearded neighborhood nerd much less than most companies. Even if I probably am that person in my neighborhood. But nobody should trust me, and I am not going to tell them to trust me.

Even if everything is encrypted, I can almost guarantee that the community shared server will be confiscated by the police once in the next three decades.
