Note that you don’t know what the hosters know, store and/or sell about you.

I’m glad that you see my point that “other people hosting your data” is not really a good idea.

They host software for anyone to use, and capture all the data, usage patterns, etc, for themselves, to use for their benefit, and to use against you.

So I guess that we can agree that data stored on other people’s computers will not be safe. I honestly wonder why you think other people’s computers are safer if you know their names.

And you want to sit here and tell me they’re the answer?

I would be very grateful if you would only judge what I have written and not what you think I might have meant.

Are you just an apologist for FAANG, etc?

There is no reason to attack me personally, my friend.

Who’s paying you to post this disinformation?

Just in case I’m fundamentally misunderstanding your personal attack so I don’t report it to the moderators without cause: What is ‘disinformation’ about my pointing out that Google and Facebook host software for other people (even if they have their own motives)?

every community has somebody in it who does the self-hosting for the community

That’s what (e.g.) Google and Facebook do: Host software for the community.

You can’t extend, modify, or customize hosted software. Self hosting FOSS applications addresses all of those.

But:

rather than expect everyone to self-host, we should be working towards communities offering services to one another

How exactly are “communities offering services” a different thing than “hosted software”?
