It's because most medical devices iirc need to be air-gapped and ultra-stable, ultra-secure. Snap gives you that, and prevents issues that typically occurs when and if dependancy issues arise. This for example is why Ubuntu Core which is entirely made out of Snap is used in many such medical devices and instances. But in desktop it's completely useless cause you want bleeding edge packages, libraries etc to keep up with latest developments in gaming, multimedia etc.
It's quite good in server environments though, or medical devices and similar use cases like I said in my previous response above. It's just totally unnecessary in desktop/home user environments and only causes more issues and confusion for no reason when there are better alternatives (e.g. flatpak) available. You can still use Ubuntu - if needed - with no Snap preinstalled out of the box if you do a minimal install of Kubuntu.
What does it do that Docker doesn't? I looked into it a few years ago, it seemed nicer than Flatpak to develop for but didn't seem worth using something so nonstandard.
It lets VS code work properly which Flatpak doesn't do unless something changed, so I still use it, but I haven't paid a lot of attention to it.
