I think it's right. Countries have sovereignty over their physical territory and they ought to have sovereignty over their digital territory, that's the basis of any democracy and self-determination.
Of course it produces awful results in Turkey because Erdogan is an autocrat, and autocrats use power to enact dumb policies, in this case censoring something because his family was insulted.
However in democracies it is necessary to not be defenseless and to maintain values. Here in Europe I've always felt that we're pretty much exposed in the digital sphere to either American norms due to sheer size, and nowadays more and more to negative campaigns by countries like Russia and China as they've learned to weaponize cyberspace.
