Deactivated my FB account years ago. Let me tell you, you don't need an alternative.
I see comments like yours often, it's just that it never really leads to anything productive for those still trapped in the cycle. They just see outsiders from their POV, who don't do what they're doing. I don't think the average social media users is that cognizant of the behavioral modification possibility of using socials in the first place, or even of advertising in general.
