They say this:
> While the software is an essential part of the Oxide cloud computer, what we sell is in fact the computer. As a champion of open source, this allows Oxide a particularly straightforward open source strategy: our software is all open.
But their homepage says this:
> As soon as power is applied to an Oxide rack, our purpose-built hardware root of trust – present on every Oxide server and switch – cryptographically validates that its own firmware is genuine and unmodified.
That sounds like tivoization to me. The value of their software being open source is heavily diminished by their hardware refusing to run anything but their "genuine and unmodified" software.
