problem with that is: so many come from china and the sellers are like cockroaches when the light comes on; they scatter, change names, go out of business and resurface.
there is next to zero ways to punish china based sellers and 99% of them are engaged in selling fakes (of anything, not just chips).
suppose the chip is soldered onto a system that can't easily be fixed? is ftdi going to do the rework? zero point zero percent chance of that happening. so, them sending you another 'chip' is pretty useless, in practice.
shaming the sellers usually wont' work unless its a perma business like sparkfun or adafruit. amazon and ebay sellers are like cockroaches, as I've said. you can't kill them all.
all you could realistically do is give a tool to end users to DETECT fake chips. then, next time you buy one, you run the test and you have a few days or weeks to return to the vendor (while they are still around and in business). then again, ebay would have to ammend its policy to NOT require you to ship the goods back to a china seller, or at least send you a prepaid shipping label.
in reality, I see none of this happening.
best I can do is stop windows update from now on (MS lost all my trust on this, forever, at this point), install 2.10 on my win boxes, lock them down and carry on with my life.
oh, and all ftdi designs I had in progress are now being modified to use another chip instead of ftdi. I may have to buy ftdi's on arduino nanos (I like them...) but I won't DESIGN with the chip in my own embedded boards anymore.
