This is a flawed viewpoint. The idea that any single company can stand up to a nation state is absurd. The level of resources that Russia or China brings to bear for a single hack is far beyond what any company or even groups of companies could defend against.
This is the unfortunate weakness of the Western style democracies in the face of totalitarian states. We have a much more obvious divide between private and public entities. In China and Russia, the lines are blurred and often they get much better support from the government to defend and hack the opposition. Even to the point where China will hack US companies and just give the IP to Chinese companies.
Not to the level that China is doing it, that's for sure. Just by the very nature of how closely companies in China operate with the government, you'd be fooling yourself if you think that's equivalent.
