Even places like lemmy or mastodon aren't safe anymore. Everything that is public can be, and is, data mined by some corporation. There will be bot accounts or paid people pushing their agenda. And several other things.
It's not a technical problem. We can have places that are better than the average, but the corporations will still put their tentacles in.
Nice article! Are you the author? If so, I'd like to give you a suggestion: the part about the deepin Linux story and technical background is interesting enough to be its own article. That way, it would be more findable on web searchers and probably help a lot of people who look for information on it, which is a bit scarce in english.
