They could, but they're pretty much guaranteed to not be as bad as the big corporations because they lack the resources and know how. The fact that you could also host your own instance is a huge plus considering that you could basically ensure that your data won't get collected.

Lemmy is basically just a decentralized clone of reddit. A public profile containing comments, posts, upvotes, and the like are considered an integral part of the Reddit experience. I personally don't like it as a feature, but that's why it exists.

They're private in the sense that there isn't a corporation stealing your data without your knowledge, selling it without your consent, whoring you out for ads against your will, and/or making your experience shittier to manipulate you into buying their paid features. These alternatives offer a much more pure experience for the typical user. Things like comment and vote history being public is just a part of the design of the forum, they're not tools to farm your data.

I agree that it shouldn't affect existing family units, but at the same time this isn't anything unusual. The non biological parent has to go through the normal adoption process to be considered a legal guardian. The same thing should apply to heterosexual couples where one, or both, of the parents aren't the biological parents of the children.

That's also true, but I find the ability to decide what gets blocked and what doesn't to be useful sometimes

Turn it on them. Ask them to give up something private in front of you like their phone or wallet. Hey, if they have nothing to hide then they shouldn't worry... But they will.
