Lesson 1 about competing with Google should be "don't be even more disrespectful to your users than Google is". Otherwise people will just use Google.
Relying on the goodwill of a small number of "never-Googlers" to carry your business, in spite of the way you do business, is not a path to success.
While hCaptcha trashes its reputation, the rest of the world will go on using reCaptcha and not giving the faintest whiff of a fart about hCaptcha's existence.
(Side note: the spelling is "intentional", not "intensional". Think "intent" + "-tion" + "-al", not "in-" + "tension" + "-al").
