As a generalist I have to learn many concepts and dont have time to delve into any one that deep. Flatpak works and isnt proprietary like snap so I enjoy that. My recent debian+kde installation works well with if. Open discover and install flatpaks as much as you wish.
The Snap Store is run and controlled by Canonical and is not open source. The rest of Snap is open source, meaning the daemon and core software. [emphasis mine] How threatening this is depends on you POV and has been the subject of much discussion.

Exactly, proprietary.

Exactly, proprietary.
