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)
"The ends don't justify the means" is also a principle. And it's a good one. 'Many a great evil has been done in the name of good' etc.
If someone won't kill their grandma for one billion dollars, they probably won't do it for 10 billion either.
