They will probably come back, under a different name, in the future, at some point in time. None of the Chinese vendors are here to stay long. What they're doing is highly illegal and if caught, its the end for them. It's China. The more well known the name, the bigger the operations, the longer they operate, the higher the chance of getting caught. Once things get too hot, they will leave (exit scam maybe), take a short break and come back as a different company.
Here for a good time, not for a long time.
