OK, I did something wrong and have over-reacted. Our heartblood is put into this product, we all heavily take care of it like if it was our child - we love what we do. Thats why I over-reacted and took it as a direct attack. My point of view was that if someone writes you, that he/she does not respect your Copyrights, then this person may have some illegal plans with it. And of course at this point I was like: WOW - I need to protect my product now. As said, English is not my native language, and it is hard for me to express myself in English.
We really care a lot about our customers. We help where we can. I did something wrong in this case as mentioned above - but please do not blame the company nor the team, nor the product for this.
