While it would definitely suck if these companies took on policies for the sole purpose of promoting the interests of another company, regardless of damages it might inflict on the public. We still have a choice to use another service.
If Google can't find what you're looking for, we'll find another search engine. If Facebook is stopping you from sharing information with your friends, people will find a new medium to share that information over. If banks stop processing payments... pretty sure that is illegal, so after switching to a different bank, and possibly pressing charges against your current bank, that would be resolved as well.
On the upside, when sharing something that *might* be protected by copyright is blocked, at least it won't be a criminal act that will put you or your loved ones behind bars.
