No, there are good reasons for it. A lot of people get confused between SUSE and openSUSE offerings. Often SUSE customers show up in openSUSE places, because they believe that it's a place they can get official support. And I'm sure a lot of potential customers might get confused in the same way too.
On the flip side there are also a lot of openSUSE (adjacent) users who think SUSE is (secretly or not) making openSUSE development decisions or think they can dand SUSE to do that and that.

So there are some good reasons to consider a rebranding, but also some speaking against it, like the less of recognition it might entail.

And you really think, people who are willing and able to buy enterprise support for their Linux distro get confused by the naming?

No, I don't think that. I *know* that because I'm active in the community.

OpenSuse is essentially free marketing for SUSE, nobody would know them otherwise.

That is absolute nonsense. SUSE mostly serves large enterprise customers. That's an entirely different demographic from people who care about Desktop Linux or setting up a home server.

Edit:

its market share is relatively small compared to Red Hat or Canonical.

I'm pretty sure SUSE is bigger than Canonical.

Editedit: According to wikipedia SUSE's revenue is about twice as high as Canonical's

I'd say it's non-mouse focused. Heavy touch or keyboard focus work pretty well, but the mouse really isn't intended as anything more than a helper.

That could be a branding strategy, I guess, but the community project behind it will still need a name of some kind obviously. Unless they only want to show up at conferences/have a website url etc as "the project whose name shall not be mentioned".

SUSE isn't owned by Novell anymore though. So this isn't particularly relevant.

And where do you think the people deciding what to buy get their information? Mind share is important.

Most certainly not in Linux distro community spaces, because those are completely irrelevant for them and their needs.

There is no "current proposal" at this point.

Mobian developed for PostmarketOS? I feel like you are mixing something up here, as those are both distros. Maybe you mean Phosh?
