I'm not sure that the fact that corporations sometimes fails disproves that they are evil or proves that they will not screw their customer's over. As an analogy: criminals often go to jail but that doesn't disprove that criminals exist or prove that they won't victimize people.

I'm also not sure that I agree that more deceptive companies are failing in favor of more honest ones. It seems to me that many modern business models make use of questionable strategies such as dark patterns, regulatory capture, and vendor lock-in.

Perhaps the greater point is not whether a corporation would take advantage in a specific situation. Rather the larger point could be that, due to their size and distributed nature, global corporations are not accountable in the way that individuals or local businesses are.
