US social media companies contributing to widespread social unrest that ultimately led nowhere[0] or created more oppressive Islamic regimes and sectarian violence - well, this seems like an argument against TikTok, not for it.

Despite any personal romanticism towards violent revolution you may have, that is not something that societies actually want against democracies. Even against authoritarian regimes, society often goes from bad to worse (see Iran, Lebanon). You want violent revolution against actual oppressive regimes, not democracies where you can change the society with a vote, but even then, you want it led by pro-democratic factions.
