Openstack implementations from Ubuntu and RedHat are most closely aligned directly with features. They also offer commerical support models which is critical for enterprise businesses. Proxmox is pretty pale in comparison feature and usability wise but I'm seeing lots and lots of people flock to it in home labs which means it stands good chance of growing.
Hyperconverged models from Nutanix as an example have also seen prices surging to the point of absurdity. The major commercial entities all seem to be pushing enterprises into cloud computing whether it makes sense or not. Cost estimating in cloud land is quite a bit harder to do since you have to pay for every little thing you use.
Historically new technology make doing this cheaper, that is no longer the case. Openstack and the list you posted seem to be gaining in popularity as a counterweight to these changes.
