They also do this thing now where they block [1] smaller browsers (even ones using the latest version of chromium) under the guise of security. According to their docs they're fighting MITMs by generally disallowing any browser they can't identify (so the big few).
If you're not on a whitelisted browser by Google, you can't log in (effectively, use) any of their properties.
This feels very anti-competitive to me. Notably all the whitelisted browsers are either theirs (Chrome) or sell them their search traffic. I'm building a browser for research [2] and have to frequently find workarounds. I'm not quite sure who I'd contact to get on said whitelist either...
