It was not respectful and that may be a communication problem:
Don’t be one of those 55% of folks that do not appreciate open source products.
I’m trying to be nice about this, but as this is taking a few posts too many to explain, I will just say this. Please do not attempt to make this personal. The reviews are just an expression of someone’s experience with yours of other people’s plugins. If they’re posting a negative review then they have usually had a genuinely bad experience and there are learning points from that. It’s not personal, i.e. it’s not because they don’t appreciate open source.
