Help me understand. Why would you install a distribution, just to gut what's making it what it is, instead of just getting anything else? Just from Debian derivative perspective, if you hate snaps, why not install something like LMDE Mint, if you need a complete out of the box distro?
I think mainly because a ton of open source software will be tested with Ubuntu, and I don't want another thing that could possibly be the problem when it fails to build on my machine.
Problem is that by "unsnapping", you deviate from "Ubuntu". You start having to add all sorts of third party packages, and the more that is needed, the more the value of aligning with a well tested baseline diminishes. Notably, Ubuntu declares an intent to make everything snaps, including the kernel and bootloader.
So it would seem more productive for someone railing against snap to avoid using Ubuntu and avoid bolstering the reputation of something they fundamentally disagree with.
