> the entire Linux ecosystem is gradually becoming RedHat ecosystem. No. Suse still exists, if you don't like Debian based distribution. But my money is on the Debians - and more specifically, on Ubuntu. For server stuff, Ubuntu is great - commercial support with various cloud providers, lots of prepackaged software (including the commercial software I use). For hiring, a lot of students run either Debian or Ubuntu on their own computers - meaning I don't have to teach them the intricacies of rpm like apt search is rpm -Q, apt install is rpm -i ... Icing on the cake is ZFS as the rootfs filesystem out of the box since the last few Ubuntus. RedHat was innovative, like when they replaced ext4 by XFS as the default filesystem, but that was like 15 years ago. Still, big money make miracles happen. If IBM can arrange some relicensing of ZFS with Oracle, they could use it on RedHat, but it'd take me a lot of cajoling to even consider switching back - much more than a filesystem that's the minimal prerequisite to just put RedHat on the list of options. Bitten once, twice shy you know? Anyway, given how it's favored for WSL, Microsoft will eventually fork or buy Ubuntu from Canonical or just buy Canonical outright, which will make it even more of a rival to RedHat in the long term.
