Aside from some confusing marketing...
...where it is sometimes positioned as a management tool for multiple Linux variants, and in other places it is said to be a fully compatible replacement for RHEL -
I doubt many paying Linux customers would trust Suse to do this for supporting applications running on RHEL.
Also, Suse, if they clarify that they are making a RHEL clone, would have to try and get ISV and IHV ecosystem of vendors to support their Liberty version, in addition to their paid Suse version. Most of these hardware and software companies have a limited support matrix they are willing to do, even if Suse says "it is the same as RHEL".
It feels to me like Suse was pushed by Google and MS Azure to do something like this to battle AWS Linux and replace CentOS. But if the financial people do the math on selling a fully free software product - 1 million units X $0 is still $0.
Grab some popcorn and watch the show.
