There have literally been times where I debated whether or not I wanted to purchase something because of the knowledge that I would have to solve Google's captcha. Humble Bundle, in particular--the login process for me (due to uBlock+uMatrix installed) is like this:
1) Try to login
2) Login doesn't show up--go to uMatrix and whitelist some crap.
3) Try to login again.
4) First phase of login completes, now blank when site tries to load Google captcha.
5) Whitelist Google captcha frames in uMatrix and reload again.
6) Login for the third time, Google captcha now displays properly.
7) Spend 10 minutes solving captchas. If I'm lucky, the first "Verify/Submit" will work. If not, I probably need to whitelist cookies for it within uMatrix and reload/try again.
8) Get notification from HumbleBundle that "You have not logged in from this browser before" and wait for a Verification email to hit my inbox.
9) Enter verification code. Site usually then logs me out for some reason, even though it was successful.
10) Login again. Solve Google Captchas again. Finally allowed to login.
11) Finally buy the goddamn thing I was there to buy.
Funny you should mention that, I actually wrote an email to support asking them to have frickin mercy with the google captchas. The response was as you expect "we do this for safety and protection, yada yada" which to be fair, I obviously didn't expect them to change anything, although I hope it did help raise some awareness.
The interesting thing I got out of it was that they mentioned that google captcha for logging in is disabled so long as you have 2FA activated on your account, which certainly helped, at least a little bit. You do still have to use the captcha to buy anything from the bundle (at least if you're using something like paypal, anyway).
I've emailed them about it as well. Totally sick of having to grind through Google to sign in to HB, I've not bought stuff because of the effort too. I also really don't think it's appropriate to include Google as a third-party in login processes anymore.
It always amazes me that companies, especially those that know their audience is tech savvy, don't test their sites/shops/systems with common things like ad blockers or privacy plugins. I often run into hidden problems on sites that go away after I allow some third party domain.
I wonder if it's just incompetence at the developer stage or a management decision to annoy users that have ad block etc. Neither really makes sense, I'm a paying customers, they shouldn't take it personally that I don't care for ads, and they are multi-million (or even multi-billion) companies, surely somebody there knows that ad blockers exist.
I _have_ multiple times walked away from a purchase due to reCAPTCHA at the login form (Sony - PSN). It makes me think "You know what, this isn't worth it", and I don't want to help Google out anyway.
I tried sending an email on their support page to complain about it as they are likely losing customers like me but it was behind a captchas and I gave up.
