'Everyone can use Linux. What do you need Windows/MacOS for? Some stupid game you barely play anyway? Stupid MS office apps that your company makes you use?
I even got my granny to use Linux, one day I just swapped out her stupid windows and she never even noticed.'

I see a lot of that around here. It's blatantly not true, and no not *everybody* can just 'up and use linux' so easily.
Screen-reader users for example.

I'm happy some can be so blazé about it, but when a screen-reader is your gateway to the world of computing, jumping on the Linux bandwagon is neither simple nor as easy as pie.
