Okay, but is he wrong?

I don't have a horse in the flatpak race at all since I don't use it, but the arguments on this website seem strong. I don't really care what someone's motivation for making a point is, I just care whether they're correct or not.

It's technically correct in the same way "ants suck - humans on ants racing is a nightmare" is technically correct. Whether it matters for you depends on your environment / what you want to gain from Flatpak.

If you don't use it (as in don't have a use case you want Flatpak to satisfy), then I think the article is neither right nor wrong.

It’s technically correct in the sense that allowing users to run arbitrary code is a security nightmare. From my own usage and assessment, flatpak seems to be more secure than traditional package managers.
