Suit yourself. Perhaps I'm cynical. Given my experiences and watching other people outsource production in China, I have learned that the cultural and ethical framework is not that same as in the western world. An employee at Siglent China would not independently start submitting DCMA/trademark requests. I can also see that when asked about it from Steve, a worker would apologize and take the blame rather than implicate their managers, letting them save face.
It is obvious to me that Siglent China wanted to wipe out the lower priced listings on EBay, and it wasn't a mistake, hence the request to raise his price.
I also think Steve @ Siglent America is now in the difficult position of trying to figure out what happened while having a conversation with the people who set forth the policy. They won't care -- they were successful in eliminating competing sales, and they only have one person complaining. Haha stupid Laowai.
Remember -- so far the resolution proposed by Steve is a phone call, in a few days. Not: 1) we're sorry, we will withdraw the complaint, or 2) we're sorry, re-list the item and we promise we won't submit another fraudulent and abusive claim, but only for you, or 3) we're sorry, we will stop submitting fraudulent complaints to ebay.
They will only change if their sales suffer. If I were shopping for some T&E equipment (and I actively am) I would like to know that Siglent is actively trying to restrict my ability to sell my equipment when I want to trade up.
