Have you used TOR and experienced what Cloudflair does? The server 3-10 tests per page requested in some instances collecting massive amount to training data; I'd in fact be suprise do if Google doesn't place an incentive on collecting as much data as possible; likely enough to ID a user 99% of the time based on the input provided by the user. As for it not being a silver bullet, it's well known that CAPTCHA don't stop bots, but mine data from people. There's not a single Google "I'm not a robot" that can't easily be circumvented, I just know most TOR users aren't able to and Google & Cloadflair are exploiting this.
