Two things to note as well:
Steve Bannon is critiquing Trump because he's likely paid off to support tik tok falling into US hands entirely even though he was singing a different time before that he wanted it banned entirely. Trump has always been a broke boy that got his wealth from family or billionaires like Sheldon Adelson, so we know it getting banned outright will fuck Trump now & he only wants to save it for his own skin.
Second thing is that Bannon is wrong in thinking that Trump has never been bought out, but if he wants to take a stance against him now for even a fraction of a pico second, this could be spun that Trump wants to utilize that data collection for nefarious reasons(he obviously does); if he changed his mind on banning the app now.
So Democrats if they're actually going to do this, need to ban it outright so it doesn't fall into the hands of people like Trump or Marsha Blackburn or Tuberville, because I'd rather the app be dead entirely with the few positives it has, then be a useful tool to be bought by the likes of them or even Bobby Kotick.
