This was a huge own-goal for their brand image.

If I buy a FTDI based adapter, it might brick, and I lack the detection skill or supply chain control to be sure that it won't happen.

If I buy a CH340 or PLwhatever based adapter, that doesn't enter the calculus.

Unless I had some explicit "only FTDI can possibly do it" need, I'm going elsewhere.

Exactly - the FTDI drivers refusing to work would have been reasonable and emitting a log or error message that my device was counterfeit would have actually been helpful. Instead, they vandalized end user equipment by permanently bricking the devices which is arguably illegal.

I am not nearly sophisticated enough as an end user to spot a counterfeit FTDI usb-to-serial device so I am not going to risk buying that brand and end up with their drivers intentionally bricking the device.
