Google doesn't care, they just want free training data. The team behind uncaptcha even gave them 6 months notice and Google still did nothing

That was v1, they shut it down in March 2018. You won't see it anymore anywhere.

That's v2. v2 will present you with a simple check box if you're very compliant with the google surveillance system, or will present you will image challenges if you're not (or if it's just in the mood.) v2 is very capricious and will reject correct answers from users google wishes to punish for, e.g. using firefox, using adblockers, using resistfingerprinting, blocking google's cookies, etc.
The recently released v3 is the worst of them all; it does away with the image challenges of v2 completely. The user never interacts with it directly, never has an opportunity to persuade v3 that they're a real human by answering any sort of questions. It's nothing more than a measure of how compliant you are with google's surveillance.
I did a very quick experiment with reCAPTCHA v3:
* using Firefox in private browsing mode (not logged-in to anything)
* with a VPN
* using uBlock Origin
* Do-Not-Track on, disabling 3rd party trackers
* Only went to one page and filled one form with garbage data
I did a similar experiment using Ghost Inspector (a platform for automating browser testing, something similar to Selenium, but not sure what they use exactly), and my scores were consistently 0.1.
I'm also a bit suspicious of Google, and have trouble with the fact that this is the only solution on the market, and it's free for websites to use. But I'm not sure your statement is entirely accurate judging from my very limited experience.
Edit: If try to use audio challenge in the first case, it directly tells me that I am using some method to solve captcha and they won't allow it. So much fun.
Google is evil.
