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.
