Companies like Red Hat, OpenSUSE and Canonical are not only trying to sell support but also convince others that they are innovating. Red Hat kickstarted Flatpak and then Canonical, who didn’t want to “lose” decided to push their own thing, Snap with the strength of ten thousand suns. Naturally, this is a simplified explanation, Snap already was in development at the time but if we truly followed the spirit of open source, Canonical would have dropped it and adopted Flatpak instead.
OpenSUSE has quite a few products in the kubernetes sector, even Oracle has its own things they can brag about. Canonical has basically nothing and this is why they’re pushing snap as if their lives depended on it.
Remember, Linus didn’t write an OS because the GNU folks were writing one, GNU didn’t write a new kernel after theirs failed, because Linus had a working one. This is the nature of free software, Canonical has completely forgotten about it. Red Hat now too.
