I feel like this is a huge risk for Apple. The president can change his mind, you can have a new president, Congress or the supreme court could decide they actually wanted that law enforced.
Also, If it comes out that sensitive data was exfiltrated from the US via tiktok, or whatever natsec concern saw it banned realizes, then Apple's position is suddenly even worse because the president can say "Apples clearly breaking the law! Lets throw the book at them".
I don't understand the risk/reward calculations Apple did that came up with this decision.
It'd be interesting to see correlations (language brain vs math brain) for how easy or hard it is for people to solve new problems with language after they already know the basics.
