> You wouldn't say that PyPy exists as an alternative to Python, would you? I think you would if Python (proper) was controlled by an anti-competitive information stealing superpower which is becoming increasingly disliked. Alternative backends to Python would be very important. Ensuring that the language is still usable in the event that the primary contributor goes full-tilt evil. With that said, i don't think it matters (personally) if Mozilla has their own engine _or_ browser, in the most strict sense. What matters is that both of those things have invested parties capable of forking and/or maintaining free and open source versions of those things in the event that Chrome (ala Google) goes full evil. It does seem that maintaining your own browser and rendering engine seem effective ways to ensuring you're capable of carrying the torch should Chrome disappear tomorrow. Hypothetically they could just maintain/develop directly into Blink and Chromium.
