Ever had use hardware that you didn't buy yourself? I don't have a choice to select Linux friendly projectors at conferences. I still wanted to have the same experience of just plugging a cable into my computer and everything working as MacOS users have.

Yes, of course. The point wasn't that I would buy a device for my own use (though that is kind of appealing these days), but rather that your choices influence what the market provides.
If you want display devices to support Linux, you need to preferentially buy devices that explicitly support Linux, and make that fact known to vendors as well as you can.
