Not installing through a package manager brings many disadvantages of Windows.

If the developer itself ships the binary, then I can not know for sure that nothing “slipped into” the package that is not in the source code. Malware is still not that common on Linux but I prefer the distributor to build packages on some kind of build system over the developer building on the PC where noone knows how well he cares to not risk installing any “fishy” software.

This is one of those rare times I’d say “no, that thing does not need to change.” The strength of Linux is its lack of centralization with several strong contenders leading the pack. Packaging is not a problem for expert users, and casual users have options. I personally think flatpak and snap are polluters and wasteful, but haven’t broken one of my systems in a while so I don’t mind using them. Options for packaging benefits both the users and maintainers; only someone seeking to monetize that wants to consolidate. Before you know it, graphical installers will have ads. Screw em

although why you would not want the latest stable version of an app for example is beyond me, like, it’s a stable version, you should want the new features

Because most developers don’t follow Torvalds’ first rule of kernel development: “We don’t cause regressions”. They’re completely fine releasing so-called newer stable versions that are less usable than the earlier ones - removing features, demanding more of the system, letting known bugs to slip through because they assume user case (“it’s fine~”).

And, contrariwise to the guy in the video plenty, plenty users know this: that the latest “stable” version might cause a regression. But they usually don’t have time and/or knowledge to check every single new version of every single piece of software that they might use. So it would be great if there was someone or a group doing this for them, while taking into account that the difference between “this shit is broken!”, “this shit is usable but worse” and “this is actually better” is subjective and depends on user case. Right?

Well. That’s what a distributor does. This is a critical role of distributions that the video does not address - they sort and trial software versions for the users, based on user case.

because they depend on all the versions of libraries that you would not be able to install on the distro because they would break your system or conflict with a newer version

If library developers did what the kernel devs did, this would not be a problem. So while the video guy is addressing a real problem, he’s being unable to pinpoint where the problem lies in; it is not in the distros, but upstream.

duplication, storage, etc.

Is the increased amount of storage necessary a real problem in 2023? I’m not sure given that storage has become dirty cheap even for users, and the cost is usually spread out among the distro maintainers.

Regarding developers releasing multiple versions: usually the ones doing this are the distro maintainers.

I’ve stopped watching the video at 4:09.
