Moral arguments about "blaming users" do not overcome the fact that the incentive structures driving these problems absolutely do emerge from the choices and behaviors of low-information users.

Viable solutions can only come from informing and persuading users to use alternative options, which relies in part on demonstrating the actual risks and consequences of the choices they've previously made (i.e. "blaming users") and simultaneously developing an ecosystem of alternative options that's sufficiently accessible to them (which already proliferate).

Lots of "normal" users have already migrated away from Twitter to e.g. Mastodon, so it's not clear why this isn't reasonable for Facebook.

People are on Facebook to scroll. For connection you have phones, email, text message, and others.
