Many can't upgrade to 11 and don't want to buy a new device. They'll believe it's their only option unless told otherwise. It's not necessarily a "Win11 is bad" or "Linux/BSD is better" scenario, just a "to keep using your current device which you paid for less than a decade ago, do the following".
Times are hard and people shouldn't be forced to buy new hardware because of the current monopolistic software companies's latest money making scheme, especially when their old one works perfectly fine and the environment is going to suffer.
I'm curious what OSs and what issues you had. If you want, make a post in a Linux community and reply with the link here. I'd be keen to see where I'm at in helping others with Linux drivers since I just had some issues I resolved. I want to move my grandpa's computer to Linux when Win10 runs out so it could be a practice opportunity.
