Every job I’ve had as a developer, I’ve had a Linux box for development. Some I’ve also had a Windows laptop for specialty hardware vendor programs / portability, and some I’ve also had a MacBook from which to work.

I’m not going to whinge just because I don’t get to use all of my personally preferred platforms, but if my employer ever denied me the necessary equipment or insisted upon the objectively wrong technology for a project - in any way - I’d simply leave if they refused to listen, since I’m not going down on a sinking ship.
