Linkedin used to trick people into thinking you have to pay to see someones profile when you can see it just fine by logging out. That is not against Googles policy. Not sure if they still do that, but I used the logout trick a lot a few years ago.

Google does document a way to mark paywalled content and have it indexed without it being considered cloaking: https://developers.google.com/search/docs/data-types/paywall...
