People switching to Linux forces a Rethink of how you do things. There is loss and change, and the mistake people make so often is thinking "I this in windows, why not Linux?". I think this is an understandable expectation because they look so similar. The trick is reaching this understanding and resetting your expectations.
I run EndeavourOS (Basically Arch), and I love it, but it doesn't do everything. I have to use windows for my music creation stuff because the instruments and effects I want can't be installed on Linux. I'm prepared to switch between the 2 OSes and I've slowly managed to move almost everything I do on to Linux by finding alternatives and accepting the different ways it does things.
Doesn't mean it will work for everyone but that's the way I think about it.
I wear whatever the fuck I want. I once had a sort of boss (not a line manager just a coordinator. Our team were all contractors and didn't really report to one person as such). She saw me crossing the office one day and pulled me aside to tell me I had to wear a shirt and tie from now on. Anyway, I just said "nope", and walked off.
She had been trying shit like this on our team for a while and we knew we could just ignore her about this stuff. Still satisfying though.
