Redhat does the same: but the license is GPL. Their trademark guidelines
clarify, that if you have changes the software, it is OK to freely
redistribute modified copies, as long as you change some small bits in
the distributions that include logos and such.

This is how CentOS and co. work. And recently a little company called
Oracle started to sell its own Redhat-based distribution.

Redhat is probably in a rather unique position where they can use
basically solely their trademark as a main selling point. Having done
that, they publish much code under the terms of the GPL, and would
always appreciate others helping them with writing, debugging and
maintaining it.


Anyway, I'm sure that this is not the right teach Digium how to succeed.
Even if they actually needed lessons.
