Yes of course the USSR could clone an 8086 and 8087. They cloned the VAX11/780 too.

But that is the technical might of a whole country.

Some chinese fake chip operation is not going to be cloning an 8087.

Btw, if you write back the old value into the fake chip (using Linux and a small piece of software), the fake chip starts to work again. So, no physical damage.

If you ask me, it was brilliant  :-DD

Technically the damage could be reversed, yes, but you're thinking about it like an EE. From an ordinary end-user's perspective, their device simply stops working, they have no way of knowing why, and it's as good as dead. Totally unfair.

Unfair from the counterfeiters, yes.

Should put a stop to the discussion on FDTI gate thing.  FDTI already a history, people are actively avoiding and their plan to dominate the USB to serial have failed miserably, almost all China gears are not using the FDTI anymore.  FDTI was not better, it was just most convenient, even then there was much cheaper alternative at that time.  The margin in those cheap gears can hardly pay for what the FDTI wanted.

Was there any significant amount of real FTDI to begin with? There were a lot of cheap "FTDI" adapters simply because they all used counterfeit ICs. That's after Prolific started fighting counterfeits with drivers. Waiting when counterfeit WCH will appear if there aren't already.

They will stamp "Intel inside" on a random mix of recycled Intel parts, second sources and unauthorized clones from the 80s :)
