This is a form of "whataboutism" Just because some countries' governments are as bad as some corporations, does not mean either should get a free pass, or that corporations are not at fault for what they do.

The GP comment opposed capitalism in general. If you want to get rid of capitalism, that implies you have to replace it with something better

Capitalism isn't a type of government. You seem to have missed the point. The ever expanding need for material wealth is what destroys. It doesn't matter by whom or to what ends or under what name.

Certainly begs the question... are corporations and governments inextricable?

Corporations are governmental creations. There cannot be a corporation without a government.
