Legal and ethical are not the same thing - something can be legal and unethical, or illegal and ethical.
What about abortion? What about regulation on what goes into your body? What about blasphemy? What about ending your own life? What about pre-marital sex? What about changing your religion? What about drawing Muhammeds cartoon? What about many other things that are right or wrong depending on who you ask?
In countries with rule of law, elections, and free press, the law in that country holds more importance than unelected dictatorships with state controlled media.
Small L liberalism has a lot of values around the things you suggest: free speech, freedom of expression, laws against violence. A lot of these values make the answers to your questions pretty easy. In the corner cases if the country has rule of law, elections, and a free press - deference to their law is probably fine (though not a panacea).
As for the "US superiority" argument, some argue that US is no different than North Korea, maybe US corporations should consider Nordic morales and laws when doing business in India then? After all, according to democracy index Norway is much more democratic than the US.
People stormed the Capitol a few months back and according to the polls a significant portion of the US population thinks that the elections in the USA are not fair and the sitting president is installed there by a deep state cabal. However ridiculous I find these claims, as you can see, it's not a clear cut in the US too. Twitter was even considered a part of the conspiracy.
Indians might ask, why should they be subjected to the morals of US deep state cabal?
Sounds ridiculous but only if you are not among the majority[0] of the Republican party voters.

I'm not sure anyone actually argues this? If they do they're not really worth your time.
This isn't "US superiority" it's about rights for individuals in a liberal society. If the US fails to meet these goals then it should do better too.

It's pretty clear cut - lots of people believe insane things, that doesn't make the truth unclear.

I doubt Indians would ask that, they might ask why a western company is aiding their own government in suppressing the truth about their family and friends dying from Covid though.
