It's politics. A while ago I interviewed for a back end dev position at this "big" company and they wanted to give me an offer at which point I made some requirements such as couple of decent monitors and Ubuntu (WSL wasn't yet out then, but I wouldn't have considered it anyway). They said no, because they were constrained by their "IT department" which wanted to install all kinds of shitty spyware as I understood. They also admitted that they lost other good developers who made similar demands like working on Macs and such. Needless to say I too declined their offer, because I'm not interested in companies with developer-hostile policies.
