it may be toothless but will they have an effect?
You're Apple or Google's lawyer - the CEO asks, should I take Tiktok down from the app store. What do you say?
Otoh there's a law and civil penalty. On the other, Trump says he won't enforce. Statute of limitations is 5 years, and the liability will exist whether Trump enforces or not. In 5 years, there will (may?) be a new president. On the other hand, trump saying he's not going to enforce may give us an out if we're ever sued over this (we just did what the Pres told us to do...).
Hard call, I give > 50% that they take it down whatever Trump says.
