Noone can challenge the government on the basis of laws, as they can be changed as needed or mechanisms introduced to ammend the law (e.g. FISA courts). You can never win against someone who can change the rules.
You can base your challenge on the constitution, but amendments show that although harder to change it isn't rock solid either, and you challenging the government is based on the interpretation of the constitution by judges (e.g. current US gun law constitution interpretion of militias).
You can base your challenge on human rights, but the US might leave the UN and doesn't care either way. The situation is a little bit better in Europe with the ECJ, where goverments can be challenged outside the framework where they make the rules.
Companies are always maximizing profits in an environment, if this means playing by the intention of the law makers, then that's it [1]. If standing up to the government because it enhances its brand (Apple security) companies will do that.
Granted, China pushes companies more then the US does, but it's not a difference in quality but quantity.
