Thoughts on RHEL going closed source ? - Mander

I’m curious about what you think on how it will affect the Linux community (especially RHEL based dustros like Fedora or Rocky).

Interestingly, I've been trying to push my HPC customers towards SLES and Ubuntu LTS. SLES has better extended support for minor releases (that doesn't cost an arm and a leg), and Ubuntu's LTS... for obvious reasons.
How has Cannonical support been recently? I used Ubuntu Server for a while, but never really needed to use my support contract, but my recollection is that it was fairly light.
