That's the problem with text. People can read things differently, when there isn't a certain tone of voice to specify how it was intended to sound. I know you weren't being "touchy", but I can see how it could be read as that.

As for the grammar, technically you are correct, however this is a special case. A lot of times when people make an acronym plural, the use an apostrophe. It's not grammatically correct, but they still do it (myself included). Part of the reason may be that the whole word is capitalized, but either way, it does happen.
