Was Vine available in China? It seems quite unlikely considering how little western social media is... so while I can't tell from a quick search I'm guessing that you really should remember that.
Ironically it seems like you and GC are on the same side (China didn't kill Vine), but you actually have unintentionally made an argument in favor of the opposite stance – maybe Vine would've done better if the CCP had allowed it to exist in China.
Ah yes, I remember when the Chinese government killed off Vine to give TikTok a head start.
