I actually assumed that this message was automated – "We found on objectionable word in your project, please don't use it."

It just seems that this problems is remarkably easily solved with a simple "We are using a technical term correctly, maybe you should consider adjusting your automated emails."

I do get the impression that people generally seem to be all to eager to take offence, and it strikes me as a bit ironic to flounce off in a huff as a result of a badly-judged automated process!
