Last I tried all three of the semi-popular formats like this, AppImage was the only one that didn't feel fundamentally wrong (though what I gather was the closest thing to an official repository for them looked sketchy as hell—somehow they copied the exact CSS vibe as a content-scraped StackOverflow spam site). But that was a couple years ago. I know Snaps still suck, but haven't messed with Flatpacks since then, so…
How many different versions of OpenSSL are running on my laptop right now? Who can say? That's the beauty of flatpak: if you sweep the problems of software management under a big enough rug, they go away and never bother you again.
but that's a problem, too.
i'd rather all things on a system be bottleneck-forced into using the latest version of security libraries that my system is actively updating; yes, this causes issues, but not issues like "There was a huge vulnerability found in X version Y, does it affect me?".
in other words, i'd rather have system breakage than insecurity. That's a personal taste, I admit.
that said, the sandboxing aspect behind 'the new ways' is fantastic.
