snap оказался не такой удачный проект и Ubuntu стали терять аудиторию.
After the initial resistance, some Linux users have started liking Snap, just as few people got attached to Unity. This is a scary situation for us. From Ubuntu One to Unity and Mir, we have abandoned projects in the past. We can do it again for the greater good.

Snap is a craft and we have crafted the Snap to perfection. We worked so hard that if anyone searches for 'how to install xyz application on Linux', the Snapcraft pages comes up first to suggest using Snap packages. And now our effort is being discarded in a Snap.
поэтому Canonical собирается пустить проект в вольное плавание.
