You're literally ignoring that the Oxide management stack is very much custom and effectively vendor-locking the purchase to be maintained by them. They are not general purpose PC servers.

You can "just" migrate away from Oxide but that would mean throwing away the hardware you now own. That's the grandparent's point; if you're migrating out of a cloud to avoid the margins demanded by the cloud vendor, now you're at the mercy of whatever Oxide thinks your support contract is worth.

Sure, the convenience may be worth it, but watch how many companies are now struggling to get off of VMWare after Broadcom moves.

This reminds me of people complaining about github being closed source and moving to gitlab, or people obsessing over terraform to avoid cloud locking.

Sure you will have vendor locking at the periferies, but the core is what's important, the guest vms. The hypervisor is whatever. If you have 100 vms running on ec2, you have done a great job of designing portable software, don't obsess over the last 1%.
