The issue for Apple, Google, Oracle, etc. is that the law allows the Attorney General is allowed to go back five years to calculate fines. And the fine is $5000 per user. Even if Trump’s attorney general doesn’t enforce the law who is to say his successor won’t too?
It’s corporate malpractice to set yourself up for even the potential for that kind of hit. Like “get sued by shareholders” level of corporate malpractice. So either it gets sold, Congress changes the law, or it’s going away. It might get a 90-day reprieve (and even that is questionable), but I don’t think the status who can go on for much longer than that.
Reality is different. Right now the CDNs and Oracle clearly trust the president elect’s word.
Enforcing the law is also about political capital and whether you want to nuke your own economy. Whoever Trump’s successor is will have to decide whether they want to nuke their own tech industry through retro enforcement.
