So, the way that it is enforced, is if the major app stores, do not remove TikTok, then they get fined a bunch of money.
> It seems TikTok would have no reason to pay for any fines from the state.
Well, ignoring the fact that this applies to app stores, companies can't just ignore court orders.
If they do, then their bank accounts could be frozen. US banks aren't going to ignore US court orders. Bank of America, or whoever, is going to give that money to the government, when it is ordered to do so.
I guess if Apple, and Google, want to shut down their US operations, then that would allow them to avoid the fines.
But, I expect they won't do that, and will simply remove those apps from their app store, for Montana residents.
