"It looks like you're trying to own your hardware! We think that's great, actually."
Apparently you need a consortium's blessing to plug two computers together now. We respectfully disagree. Tempest ships with schematics. No DRM. No activation servers. No phone-home. If it breaks, fix it. If you want to modify it, go ahead. It's yours.

We believe in the right to repair and digital ownership. Full stop.
