I think people are okay with some token amount of work to check that they're not a bot, but Google is changing that into a token amount of work to help train their systems.
I don't agree with it, but I understand it, especially if you have bad feelings about google.
I think people have forgotten that recaptcha was originally designed to help Google transcribe books for their digital library, which is arguably a public good. Now they're training their self-driving cars with it, which really just benefits them.

If they were doing it for a public library or releasing the text as public domain, that would be a public good. As it stands, it's just doing free work for an advertising company.
