The major notable case of non compliance has been Google not entering China, which I argue has been more to do with internal activism than the company's preferences. Would also say that it is harder to leave a country once you're in it than not entering in the first place, so I think Google might not have left China if that were the case.

Apple happily conducts business in China and I am absolutely certain allows backdoor access to the Chinese Government. Arguably, the US getting backdoor access is almost as bad so we should already be up in arms about this, but I don't see a protest anywhere.

Hope the new privacy and decentralization wave makes it very hard to spy on people.
