This is good advice, I just got my first pair and they make a huge difference in comfort, and being able to stare at a screen throughout the day. Particularly if you are nearsighted and already wear glasses, the need for computer glasses may sneak up on you. I found that by afternoon/evening my eyes were tired and having problems focusing on a screen with my regular glasses.
The way my eye doctor explained it, there's two compounding problems - we start losing the ability to focus up close in our 40s, and distance-vision glasses push the near focus point further out. Eventually the near point is close to or further than the distance to your monitor/laptop, and your eye muscles have to strain to be able to focus.
MSI on Windows is completely fucked, PKG on Mac has a few footguns, but at least they're universal, decades-old standards supported by mature tooling. You release an MSI/PKG, and you're done. Works on every Windows/Mac system, no issues.
On Linux, an OS with 3% market share, there are more competing standards to count: Deb, RPM, snap, FlatPak, AUR, AppImage and probably a dozen other semi-popular ones. Every individual user has their opinion (and they'll voice it!) as to which standard is the best. At best, this leads to God knows how many man-hours of duplicated work packaging and QAing. At worst, it leads to the dev abandoning the thought of Linux altogether.
Linux on Desktop simply can't move forward by continued bike-shedding over frankly irrelevant details. Even if the only rationale for a standard is "Because Mike Shuttleworth said so, and he got a phone call from Mandela in space", that's a massive improvement over the current status quo.
