Nobody uses SuseLinux any more. If SUSE gets 6 billion dollars and a private equity firm gets nothing valuable, there's nothing wrong with that.
What gives you that impression? They had $700MM in revenue in 2022 and many HPC clusters run on Cray OS[1] (which is SLES).

Not how sales work.
>> "More than 60% of the Fortune 500 rely on SUSE to power some of their workloads, according to the company."
This is an Enterprise version of Linux, and unless you are in the enterprise space you're unlikely to come across it.
Also from the article; >> "The company generates about $800 million in revenue "
So again, this suggests that people are indeed using it.
I mostly like their use of an immutable OS as base layer for the virtualization - despite the limitations it sometimes has.
I liked it when I used it, but it wasn’t really a fit for our environment from what i’ve seen.
I remember since the start that SUSE was more popular in Europe, but no way would that be the case in the US. If anything, I’d be willing to put my money on > 60% of Linux installs being RHEL/Centos rather than SUSE
Also, from my own experience, SUSE used to have nearly all of the US geointelligence processing because of the HPC connection mentioned elsewhere with CrayOS, but that went away when DNI forced everyone onto the CIA's private AWS service, which only had RHEL AMIs available. The national labs and more niche intelligence processing that can't run in the kinds of machines AWS provides still make heavy use of it.
I think Ubuntu Pro is more common in service providers that sell to enterprises rather than in enterprises themselves. It enables them to say "yes, we comply with all of these box-ticking standards that you require your vendors to have!" without bringing in much of the rest of the enterprise baggage.
SuSE is used more heavily than any of them - as others have said, they're used more or less everywhere where SAP is to be found, and they're very strong in the HPC space too.
