Yes, certainly true enough. I don't really know how that is relevant to the OPs original question though. Basically you can get knots made in China or knots made elsewhere, mostly in the EU at a guess, from badger hair sourced in China.
You can debate the quality control offered and the ethics of the work place conditions in both sources but you are stuck with those two sources. Which you choose is a personal matter.
Personally, I was pleasantly surprised at how well I like the TGN Finest 2 band in comparison to my Simpsons Manchurian badger brush. OTH I like the TGN knot quite a bit better than the knot in my Muhle Retro brush.
