"E Ink" is a company, producing displays with a very specific proprietary technology. I think you mean to say more "e-paper", which is a generic term for "paper-like" displays. And unfortunately, right now the only real competition is RLCD (reflective LCD), which is arguably not paper-like enough to qualify. Yes, it's reflective, but other than that, it's just a higher density Game Boy screen. Which is great and all, but it can't compete with E Ink in a lot of aspects. It doesn't have retention, you gotta power the screen, so no signage and stuff. It has LCD-grade bad viewing angles.
RLCDs are cool for certain uses though. For example, I sometimes choose to play on my AGS-001 over my Analogue Pocket if I'm outside in bright daylight.
This applies to pretty much all "Linux good, Win/MacOS bad" memes. I just assume that people either aren't really serious about them and it's just tongue in cheek, or they don't have any contact with regular people.
I used to work as a(n assistant to the) sysadmin and the things I got called over never stopped to amaze. For instance, there was a case when software was updated on the work machines and I got called because some lady couldn't use Adobe Acrobat. "It is asking me something, I don't know what". I come over and it's just a TOS Accept/Decline window.
Some people do not understand computers to an extent that they can lock up in a state of confusion when a button has been moved 100px in any direction from its usual position.
