Well, the usual question. Do they compliant to license rules?

I couldn't spot source in an obvious place, so your question is indeed justified.

Hi tinypoodle
A quick search of their forum turned up this response to that question:

Make of it what you will.

They can do with their software whatever they want. But what is about components they ar using and their license? This question comes up freqently, wheteher you must make available yourself source of TC and TC modules on your site if you have a TC based solution (distro, appliance, etc) or no? The final answer is always YES.

So it is a license violation.
