While it’s good that you’re avoiding most of the tracking, I think it’s naive to say they’re not successul. Like I say, so many services use Captcha, and there are many more that use it as just a back end service than those that ask you to identify fire hydrants or bicycles. You literally can’t use the service without connecting to Google.

and also how often Google asks me to prove I’m even human at all.

This is also Google using you for free labour in training their AI systems.
