MS Word opens twice as slow on Windows 11 PCs as on MacBooks, and Microsoft has no excuse

I understand that and I don't blame people for just that, but if it's just for work applications and completely separated from your personal computer, then you aren't signing into your personal accounts like your bank account, YouTube, Steam, and other non-work related stuff that could pose privacy concerns. It's not your computer so who cares lol I hate Windows as much as the next guy, but surely it isn't so bad that you are unable to do just work stuff on it. I think turning down a job over that is a huge overreaction.
Edit: After thinking about it for a bit longer, the work provided computers are probably really slow/underpowered so I get why people would hate that, but don't turn down the good money either!
