Work is for work stuff. It's someone else computer, someone else wants and needs. I don't mind if they want to feed all their data to Big Tech (On my previous work computer the only truly personal piece of data I had was my profile picture and ssh keys for my GitHub account). I don't even do web searches on work computers. If Windows is slow, I'd just bring it up to my manager and the IT dept.
On my personal computers, that's a different story.
I totally agree, but I was really addressing just having to put up with the OS rather than privacy issues specifically. My employer can take whatever privacy risks they want.
I do get your point. But all of them are fine OSes, if you just want to run some software (which is the majority of the jobs). What macOS and Windows don’t allow is true customization, aka aligning it to your personal taste. That’s not great for a personal computer, but fine for a work one. If the company don’t want to address inefficiency, that’s on them.
