Rocky is only comparable to Debian in terms of the licencing model, but IANAL. Both are owned by a non-profit organisation that can't be bought.
Would Rocky survive? Nobody knows - but that's why I said I think Rocky and Alma will pool resources with Fedora in the interests of all. R&A could just rebuild downstream of Fedora and invent their own release cycle, so they may do that.
I stand corrected that Redhat are no longer publically traded - I was misled by stock prices showing prices in months, and not including the year.
But that muddies your point even further, doesn't it? We can't see RHEL's value, nor even Redhat's. (And you did mix them up!)
