I understand why no one wants to do it. But there needs to be a non-profit, independent, ad-free social media option for young people.
No one wants the moderation and safety responsibilities of running such a network. And I just said "no ads" (and no datamining, you ghouls) so this is the polar opposite of profitable.
But, young people deserve a safe place online. "just lie and say you're 15" is a bad "solution."
With the right legal framework these networks could be run through schools.
