I would say the Steam Deck has been the major impetus for Linux adoption for a couple of years now. I know it sealed the deal for me, when I went into desktop mode and learned that KDE is basically Windows but better lol.
But Linux, particularly Linux gaming, owes so much to Valve/Proton for the direction we’re going.
I use it, I just tip way more than anyone else in my area tips. Mostly out of guilt, partially out of solidarity for the working person. I like to think my order at bumps that avg hourly rate up at bit.
