All very logical sounding arguments, but remember that RedHat has been extremely successful for like 30 years with that open source model. These changes came after the acquisition by IBM, meaning that it's likely some clueless MBAs trying to make the line go up in the short term so they can get their promotion, rather than any kind of wise leadership decision. The only reason Rocky and Alma (the evil villains stealing RH's hard work) exist is because IBM killed CentOS, effectively pulling a bait-and-switch on a huge community.

What makes this extra worrying is the important role RH plays in the linux ecosystem. When they get fully IBM'd, what will happen to Gnome, Systemd, Flatpak, etc?
