This will probably be my only comment in this thread, but I’m just wondering why the beliefs of the FSF have any relevance at all to this discussion, unless one of the parties explicitly agreed to be bound by their idea of free software. To me, they take the idea just a bit too far. I figure if someone is good enough to give away free software, they at least deserve respect and credit for it - that is, they should not have all traces of their name and/or brand stripped out.
I personally might be more understanding if, say, a FreePBX deployment were being made in a country that considers cartoon frogs to be bad luck (maybe they saw the Michigan J. Frog cartoon once too often?) but even then I would personally think there is some obligation to retain some form of obvious credit to FreePBX, even if someone feels they simply MUST replace the logo.
We don’t live in a society where, for the most part, people give things away totally free. If someone gives away something of value then they at least want something in return, be it credit for being the developer of that software or just good karma.
I mean, suppose that five years from now, one of the FreePBX developers were trying to get a consulting job somewhere and listed on their resume that they were a developer of FreePBX, and the person doing the hiring said, “What’s FreePBX? We’ve never heard of that! We use SillyRabbitBox here, and we’re looking for someone with experience on that!” How do you think they would feel?
Now, there may be a planet somewhere in the universe where everyone operates on something akin to the ideals of the FSF (and if so, I want to be reincarnated there someday, particularly if there are NO CORPORATIONS!!!). But I can think of few people on Earth who’d write a significant piece of software and want neither money nor credit. Not to say it never happens, but I think when it does it is usually for software that someone has not spent a substantial amount of time creating and maintaining.
