"Just do X" is advice that is almost always less than useful. IT departments that use Horizon with instant clones and have several compute clusters with AutoHA, DRS and NZX, a sprinkle of vSAN etc. etc. etc. will take a week just to translate all of what they need to do to Proxmox terms - and then a month to figure out if Proxmox or XCP-NG can even do all that. But if the 10x price increase is actually typically, they might actually look into it. Will still take years to migrate.
