Probably the main concern around Google is for personal accounts where it sounds like people often find no way of recovering their accounts when Google thinks you did something bad.
For business users that isn't as much the case since there are good support options and it isn't likely you'll get locked out.
Great for businesses, potentially risky for individuals.
This seems entirely fair to me. I mean, if you're scared of Google, you can use something like Okta. If it's me choosing, it's not a hard decision: I want centralized authentication, so I can quickly do blanket interventions like enabling/disabling apps, requiring phishing-proof MFA without having to do any implementation work, and linking everything to onboarding/offboarding/access review policies. And if I'm going to trust anyone's security team with this, it's going to be Google's.
