problem with that is 90% of users are windows user (not exactly but most people of the world use Windows). So, going linux will not represent all of them.
another problem with that is it will introduce too many variables for most of us (i.e. Linux has error but Windows don't) to digest.
I wouldn't mind a new tech youtuber use linux to test hardware, but if an old tech youtuber test hardware with windows and he/she is comfortable with, just let he/she be, even if you are a linux fan.
