We-ell, this thread kinda started with saying that we'll see glaring security holes with the same desktop popularity as that of Windows.

Yeah, like windows did, for a long time, and from time to time still does.

Well, then it doesn't require flatpaks and snaps to solve this huge problem, right?

It pretty much does, yes.

Well, since you've mentioned accessibility [...]

Ok. Not to do with security. Let's not get sidetracked.

Ok I'm not sure, but I think OpenBSD and NetBSD don't run any scripts contained inside packages. They are not Linux ofc

I'm not sure about the BSDs, but I'm talking about Linux. And as it stands, the package installation step is a risky process in any distro I've ever seen. You just have to rely that no mistake will ever be made by packagers, nothing will slip past them, and that they manually and thoroughly look through every installation process of every package (which they don't).

It's an unnecessary risk that gets solved by Flatpak (plus a bunch of other security advantages)

Yes, you can do that. You can set aliases which will look like whatever at all. How do you solve that "problem"?

I don't know, I'm not a security expert. But it is a problem, and a massive one.
