Linux

In my experience, the larger the company, the more likely they are to force you to use Windows. The smaller companies will be more relaxed about the whole thing.

The largest company I've worked for that allows Linux had a staff count of hundreds of engineers and hundreds more non-nerds. In their case though, the laptops were crippled with Crowdstrike and Kollide and while the tech team was working hard to support us, we were always aware that we made up around 1% of the machines they manage and represented a big chunk of their headaches.

The response to this you usually hear (from me even) is that "I don't need support, I know what I'm doing". Which is probably true, but the vast majority of problems is in dealing with access to proprietary systems, failures from Crowdstrike or complaints about kernel versions etc.

TL;DR: work at a small company (<100 staff) and they'll probably leave you alone. Go bigger and you'll be stuck fighting IT in one way or another.
