I don't know the answer to this, but I suspect it may have something down to the difference in penalty for fraudulent behaviour. At the very least, if the only penalty is getting booted off the 'platform', getting added to Uber's platform is relatively cheap. Getting added to the black cab 'platform' requires getting licensed, which takes years and costs a lot of money. I'd imagine that fraudulently impersonating a black cabbie comes with significantly more penalty than getting 'booted off the platform' (license revocation).
