You can recognise some laws are good for everyone and some as unethical - it's not an invalid position. For example (on an extreme end), I believe murder being illegal is right, but pot possession being illegal is not. In the less extreme middle, (and more contentious) I believe antitrust laws used against google are sometimes good and restrictions on access to / use of publicly funded research is not.

You should comply with the laws of the country your operating in, yes. Google has different versions of its offerings for different countries, as it should be. She changed scihub for everyone, though, not just Indians, that's the difference.

Everyone loves an underdog.

Those are completely different situations. Google should obey countries they earn money from. Sci-Hub doesn’t make money.
