Professionally, the company I'm at ditched ubuntu in our CI builds because of snaps.
The packaging is very limiting, and I don't want to have to fight against the system to get a version of software installed that works.
I personally used to run MicroK8s (snap based). I finally gave up about 6 months ago. Were snaps the root cause? Eh... no, the root cause was dqlite synchronization problems that I was tired of dealing with, but snaps made the whole process so much worse. They're hard to automate, they're hard to interact with using normal tooling. They just aren't part of the system in the same way, and while I understand there's value there (hell - I'm running containers and microk8s for a reason) there's also pain. K8s was an okish trade on that front: I felt a lot of pain and gained a lot of value.
Snaps seem to be falling into the worst possible spot: I'm feeling a lot of pain and the product is usually not any better at all (and sometimes much worse).
HA Microk8s with snaps and nvidia-container-toolkit (The GPU addon) just isn't all that stable (I would consistently get hard lockups on some hardware). That same hardware running Arch and k3s is chugging away beautifully.
So maybe it is an echo chamber - but the echoes I keep hearing are system admins saying this is making life harder and they don't understand the upside, and Canonical pushing forward anyways.

So maybe there's light at the end of the tunnel somewhere for snaps. Maybe the grand vision will eventually come and folks will be fine with it. But my suspicion is that Ubuntu is being replaced at most orgs before then.
Steam is throwing weight behind Arch (LOTS of new linux users coming in here). Alpine is a strong contender in containers. Nix is interesting.
Both Flatpak and AppImage seem to achieve the "easy user installs" part without all the pain of snaps, and they're neutral on whether I use them or not.
Basically - if snaps were so good (even if they're only good in some cases) I would expect a conversation about snaps similar to that of SystemD - Strong arguments on both sides, real advocacy from the community for the product, even if it's painful to adopt, or doesn't meet all user needs.
Instead snaps are just "meh" all around. There's a steady stream of folks leaving, and no real advocates outside of Canonical. At most - you have neutral folks like yourself who just don't mind snaps.
To me - that's a bad sign. I bailed. It wasn't worth betting my personal projects on. I've been pretty happy with the decision too.
