Hey Emu-Lator,
It's not personal; you may or may not be aware that the company that produces the product you are (planning on) selling has a deservedly bad reputation. They have released products not fit for purchase, stolen source code and released software in violation of its license, deceptively sold re-branded A320's that had broken features etc. In short, they've burnt a lot of people. Hopefully this helps you understand some people's reservations.
So, enjoy your stay here and know that you are welcome. I don't think it's fair for you to be poorly treated. Just don't expect an overwhelming amount of sales or support for any Dingoo Technology product.
