If enough users are destroyed, advertisers (social media's real customers) won't have sufficient markets for their products, and profits will fall. Social media can't destroy its users and survive.
Seriously though, I disagree. Social media in a profit-seeking system can work if the users are the ones who pay. The easiest way for this to work-now that net neutrality is no longer a thing-is bundling through user's phone bills. If Facebook et al. were bundled similarly to how Netflix, Hulu and other streaming apps are now packaged with phone plan deals, then the users would be the focus, not the advertisers. This might require that social media be legislatively required to offer true ad-free options, though.
