People using Meta products are not making an arbitrary choice that happens to be evil. They are using Meta because other people are using Meta (network effect) or because it helps them calm down after a long day (addiction).

You can say they are "technically part of the problem", as in, their usage supports Meta existence in some micro way, but that doesn't warrant the harsh phrasing you've presented in the original comment.

Punishing addicts doesn't solve the social problem of addiction, in the same way that punishing homeless people doesn't solve the social problem of homelessness.
