"Developers" are a miniscule share of "enterprise". We are talking about the billion computers on corporate office workers' desks, not about the maybe-a-million computers of web/network/systems developers.

Counter-anecdote: every place I worked at including 4-5 major companies in various industries had compulsory windows desktops for everyone. The few of us that also had a Linux (or AIX/HP-UX/...) machines that we did our work on, SSHd into those machines.
