No one forces you to use their product and given Linux and GNU's raison d'etre and success it's hard to imagine any commercial product ever could become a monopoly in devtools.
So after that I'd look at: historically has a venture capital firm ever funded innovation? And I think the answer is yes.
So worst case they have a spyware product you don't need to use. Best case they actually innovate.
I'm cool with letting that play out.
Not that I think this thread on HN or my opinion makes any difference to what these companies do/don't do. :)
