I presume there are legal safeguards, but what would prevent ByteDance from #yolo and turn the entire platform into an overt anti-Trump/Republican advertising network for the next 90 days? I mean, what's the gov't going to do---shut them down?

I just remember in NYC when Uber added a "De Blasio" (the mayor, who was in the pocket of the local taxi cabal) mode (in addition to Economy, XL, etc.) that had higher prices and longer wait times.

EDIT: In fact, they probably won't even need to be explicitly anti-Trump. They can just turn the entire app into a get-out-the-vote campaign aimed at a young, mostly already anti-Trump user base.
