I wouldn't say Google is monopolizing captcha, its that captcha is hard and you essentially need to come up some expensive problem that is hard for computers but easy for humans. Personally, I hate hCaptcha more than recaptcha, Craigslist uses it for their contact forms and I hate. hCaptcha is much more difficult and tedious than recaptcha.
