Money can be used to better realize your principles. It's sort of like the trolley problem. What if you were being offered so much money that you felt you could achieve a greater net good with it than without?
I think you're arguing something entirely differently.

You're acting as if myself or the parent comment think everyone in business is evil. AFAIK you have no intimate knowledge about the founders and their motivations or what they believe to be "good", seemingly that they have some benevolent worldy principled intentions. At no point am I arguing that people don't have principles, just that those principles may manifest themselves in different ways (as the parent pointed out, the owners might sell and start a non profit privacy based solution, just like, ya know, Brian Acton did)
You can negative-buy someone. Meaning: you can pay other "actors" to make their life so miserable that they will consider selling (or conceding whatever you would be asking of them).
In that sense, everyone has a price. It just doesn't necessarily go directly in their pockets.
No. You really can't buy some people.
Either because they already have more money than they know how to use, or because they have, you know, principles.
