Controversial take but...
Yes, tiktok has several serious glaring issues as a platform but being such an absolutely huge platform, it has been (for a while now) much more than teen dance app. It's a platform that under represented and minority groups have found an audience to share their voice. The are legit journalists, artists, celebrities, organizations, dank memers, etc using the platform for good.
Obv it would be great if it wasn't all on tiktok (isn't there a federated equivalent?) but seeing people rejoice wherever something bad happens to the platform just lacks... nuance I guess. I know it's hard to compare social media platforms, but from what I can tell it's one of the less controlling, censor heavy platforms. And it's not owned by Elon Musk lol
