99% companies have been using Windows for the past 30 years. I would gladly accept any job using Windows, even more if they paid well. I hate Windows way more than everyone else, but being unemployed is worse nowadays.

I haven’t found a company that enforces windows of everyone. Seems ridiculous. I would sign the contract then simply require a Mac because I don’t know how to use Windows. IT be dammed.

Smaller companies, maybe. But bigger companies will have a ‘Security and Compliance’ department which will force everyone to use a company-supported platform. It goes beyond OS too. Unapproved apps, even if you are allowed to install them, may not connect to company resources.
