That's fair. I consider calling anything, be that GPL, BSD, or open source as poisonous as to be on the side of derogatory term, similar to the cancer comparison made by Steve Ballmer. I can see however if that’s not always the case for others.

Just as a side note, I found an half year old HN article which talked about the BSD requirements, with suggest that one might want to use ISC license in some cases: https://news.ycombinator.com/item?id=5798431

Not that your project is code for embedded software (or is it? C code tend to be quite fast and have small memory footprint), but it might be an interesting read.

We designed and coded it with embedded in mind. We both have extensive embedded experience and it was a no brainer with all that hype about "internet of things". Our stack is naturally born IPv6 and as such is a natural match for "things", so not thinking about embedding would have been clearly a mistake.
