the last thing printed is:

okay. I mean, I'm happy to keep fixing regressions and figuring out
what's wrong with booting the devices and such if regular users come
around and file bugs. And until today I wasn't really aware of anybody

It's just not worth my time, if there are no users using them at all.
Or rather.. if there would only be commercial users (like.. companies
deploying those for money), then they could get involved and help us
out, because I wouldn't be willing to spend my time on this, if that
would be the case.
