I don't know why they chase other products when they could take both of those and have some sort of premium additions to charge for. I pay for my mail clients, my calendar clients, and would pay for a browser with extra features / extensions.

Focus on the things people are using and not on becoming a VPN provider.

That said I like, and use, Firefox for all of my work related tasks. And I have nothing against them having "too many employees". A non-profit providing jobs is not a bad thing and feels like the best of both worlds.
