The surveillance capitalists control the browsers. You can only be as effective in policing them as they allow you to be (see what’s happening with Chrome, etc.)
And it doesn’t even have to be free for this to apply. Venture-capital-funded is the core issue. Because with VC you’ve already sold your company,you’re just waiting for the sale to mature (the exit) – which it will do if you’re successful.
