It's not just saying "Hey you, go fix that." , it's saying "Hey everyone viewing this comment on a public page : this exists and needs to be fixed. Someone grab a wrench."
So sure, things are fixed at an astronomical rate, but that's because things are also decaying at an astronomical rate so there's a constant supply of low hanging fruit

Or if you prefer to jump on Apple's bandwagon about how regular computers are outdated, a detachable keyboard and mouse for an Android 10"/12" tablet.
Huh? Linux is behind both Windows and OS X in most non-server related areas. They can't even agree on a good compositor...
Given that there is no such thing as just "Linux desktop" (I mean, my setup can be completely different from another persons' one), it's hard to say whenever it's ahead or behind, unless every component option is known to be such.
Well, at least when ignoring the UI/UX mention that has absolutely nothing to do with the discussion here (color correction is required in many fields, but UI and UX aren't really those ones).
The author seems to be technical enough to make a nice analysis of what's done and what needs to be done. I suspect he might be able to provide this particular fix himself - or, if he isn't, then he might be able to contribute by providing a well-detailed feature request for others to implement (with that even I might be able to go and fix it, while without it I surely won't, as I lack the knowledge, hardware and in fact even awareness of this problem; only reading this post put some light on it for me).
Some people don't do the mental switch between "I'll wait for fix" and "I'll fix it" if they're not used to it, even if they are perfectly capable of fixing it and have time for it. I see it on my own example, as there were some parts of the stack I never really considered digging into to fix stuff by myself, and when I finally tried, turned out there was no reason to keep myself restrained. It's just a friendly reminder that you can often fix such stuff by yourself and it might be not as hard as it seems.
