Gamers are probably the easiest to convince.

They already buy their console games in app stores. In two years when the store shuts down because the new gen is out, the game is gone.

They have long accepted online only single player games. When the server shuts down the game is gone.

And if they play 99 indie games and once in a while a single big name game, even though they spend more time fixing and complaining about Windows than they do playing, they will never install Linux because that one game they rarely play only runs on Windows.
