[1] Please move the "$HOME/snap" directory to a less obtrusive location https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1575053
Nowadays, processor power is infinite, memory is infinite, disk space is infinite, so why so many people complaining ? /s
I suppose this page should tell how things have improved, but its ridiculous tall cookie wall kept me out of the site: https://ubuntu.com/blog/firefox-snap-updates-and-upgrades
The issues that both share are slow starts, larger package sizes, lack of safe ways to interact with the rest of the OS, etc.
Base concept is actually really good- Separating out dependencies and "containerizing/sandboxing" userspace applications is just a no brainier from a security and maintenance point of view. Its so nice to be able to easily install several versions side by side and know you arent fucking up system dependencies. Once they (flatpack, snap, some future competitor/iteration) iron out the kinks it'll 100% be the way systems are managed.
Oh wait. You can't do that with snap. Snap is pretty much locked down, so Canonical is the proverbial troll on the bridge.
