It isn’t socialist in any way

Doesn't matter. All my descriptions match reality. And these are the terms we use to refer to these aspects of reality. Corporate socialism is very real, even if it isn't socialism. Get used to it because it's a fixture of our society.

If corporations trampled on capitalism, they would erase themselves.

Nobody in any board room will ever care about that large-scale erasure. They will each act in support of their career and their shareholders' profits. Destroying the environment may ultimately erase all corporations. They don't care. They cannot care. They are an algorithm for increasing profits. Larger ideological values are irrelevant. So-called capitalism (to the extent that it even exists) is a product of all this high-concept greedy animal behavior, not the cause.
