I think it probably does matter, as the intrusion could still be felt in various ways. For example, if kbin federates with Meta and I block the Meta instance which I assume would be huge and filled with millions, I‘d be surrounded by a bunch of people who communicate with ghosts and see things I don’t. Imagine if all top level comments in a kbin thread came from Meta, it‘d be empty to me. That is not even going into the risk of them buying out the admin to enforce various Meta rules or in other ways affecting the experience I have.
Now if that happens to an instance I am merely visiting, ok fine, but the one I’m from and mainly in, that would feel alienating.
So my goal is to be on an instance which aligns with me on this, so I don’t have to bother the pro-corporation people with my rants about the corporations either, I don’t even fault them for their view as it’s the "rational profitable majority view" in the world I guess. It make sense to accept it, but I can’t, at least not online. I just want like one space I can retreat to with people who aren‘t like that.
Perhaps I need to make my own instance if none can be found.
