Maybe the merger with Asmodee has a few unforeseen problems. Expanding market means you are also expanded to those that parasite off that market (Still going by the shoplifters are customers too modern model). I know there was C&D on shape way over them making models that were not released yet by FFG (and that was before the merger).
However taking their brick and mortar answer into account company policies can encourage counterfeiting. One of the most controversial changes with the merger is announcing to a sole retailer for all FFG products. If that causes any supply issues retailer stores might feel the need to go through other channels and thus end up with counterfeit items.
So reading back to their interview on distribution policies (the one that moved everything to one distributor) I can't say I feel sorry for them. I can't even say I buy the message. So maybe counterfeiting is just them reaping what they sow.
