If I were in John's shoes, I'd feel the same way. Personally, I'd have more respect for Tranzeo if they complied with the GPL and BSD licenses. The ER1000 series is Linux-based. Nowhere in Tranzeo's documentation or on their web site do I find the information required by the GPL. If one gets into the unit, the information required by the BSD license isn't there either. We (LCWA, that is) have talked to them regarding this and they're basically non-responsive.
To many, it's a small thing. In my opinion, it matters because it speaks to ethics. FWIW.
