My guess is that our employee contacted eBay and asked to have this ad taken down. The eBay letter appears to be a form letter or request - it even has the name of an employee who has not been with Siglent since February of this year. I don't know where DMCA first showed up in this thread but I can be fairly certain that she was merely asking eBay to take it down, not to make any threats. The letter does mention "intellectual property rights" but this does appear to be a form letter from eBay.
Again, I am guessing here, but the fact that people say it is unusual to see used Siglent equipment on eBay suggests to me that this helped to lead to her mistake. She obviously missed the fact that it was clearly marked USED.
Ok, that's a guess. The interesting fact in my eyes is actually that this seems possible in any way, even guessing!
Which right is being stressed to take an auction don on eBay? Ok, let's sum up:
- Copyright infringement
- Stolen goods
- Illegal goods (including fake products)
- ethically or sexually problematic goods
anything else?
In no way I can imagine that selling a Siglent instrument (used or new, doesn't matter) comes even near one of those points.
So there is not even the slightest idea of legitimation visible in my eyes. The described behaviour is at least arrogant, stupid and illegal!
I will stress my opinion again. I noticed, that the level, what is considered cheating versus illegal differs quite a lot in China compared to western countries. And even when they clearly know that something is illegal it rather stops them from doing it anyway. "Cheating" is some sort of common sense or sports if you will amongst chinese management.
Therefore I think it is of no relevance who that woman is who talked with eBay and which terms she exactly used.
The fact that she contacted eBay in any way is already enough to assume, that the Siglent management has - well- still to learn quite a bit. And how they will learn I said before.
