I wish more people said no. However, the reality is it appears to be a given. If you're offered millions and millions of dollars, most people do not say no. The world is worse for it, but it's the truth.

I think you really need to reconsider the definition of a given. Because most people don't say no to a thing doesn't make it coercive. Whether the world is worse or better for it in this context, I can't be sure (though I lean more towards big corporations eating nearly all competitors as generally dangerous), but we're still talking about voluntary choices in a market where competition still does frequently emerge to overhaul what's established. It's impressive how often people don't notice this even as it happens all around them in ways that directly benefit their daily lives.
