I have no issues with most of them, but Ubuntu and their snaps… no, thank you.

sure, wayland isnt perfect and will never fully replace x11, but it does just work for most people nowdays

is systemd that controversial? seems like a loud minority imo, most distros use it

gnome haters will always be there, im one lol, but its pretty fine if you like it

most of the hate twords ubuntu is directed at canonical not the software imo, but snaps i totally get, arent even fully open source with canonicals proprietary snap repos

Speaking as someone who doesn't use any of these things, at least half the problem is the people who push these pieces of software. Hint: telling someone "oh, your preferred software is crap, use this instead" when what they have is already sufficient for their purposes makes you look like a liar and turns people against your message because they don't like being insulted. There are examples in the comments here already.

There is a type of person who instantly jumps on new software because it is new . . . and y'know, that's fine. We need those people, or software will never improve. However, most people don't think that way and need to be offered a compelling reason to change. "This new software has this great new feature" may be a compelling reason . . . for someone who needs or can use that feature. "The codebase of the software you're using is old and crufty and not attracting many developers" is not a compelling reason as long as there's at least one person around providing needed patches. Even "the software you're currently using is completely unmaintained" may not be a compelling reason if the software continues to work and doesn't have any known major security issues.

(Note: I've not watched the video yet, but this is what I think of common hate towards every project mentioned)

systemd hate is just "fans" of the UNIX philosophy complaining that "it does too many things to get it right", while they follow a flawed philosophy and also fail to separate systemd the init and systemd the project.

Wayland hate is just silly, yeah it's not the same as X, but it's getting there while still avoiding becoming a total mess of software. Same with flatpak.

Ubuntu and snap hate is deserved because of how canonical is steering those projects.

GNOME hate though... I can totally understand the dislike for it. It can force too many opinions onto its users with not much choice, but thats kinda its thing, having a simple and consistent desktop experience. I kinda like their approach to a usable desktop.

Truth be told, we've got a bunch of folk who enjoys yapping "way too much", but... most of those "criticism" are valid and should be taken into account -- Gnome is indeed bloated, and Ubluntu is both bloated and tries way too hard to be "the next Windows" with telemetry and the focus on software that gives the same "Windows-like" experience.
