I agree with what you have said. It's what you mentioned at the end about people judging based on metrics - it should be up to people to judge for themselves, not the platform! The platform should present data, not try to sway opinions. Besides the message itself is so hand wavy if I am using the phrase correctly, what is Google trying to convey through the message? If something is a legit scam, they should either not be publishing such apps or be testing and removing them.

I am increasingly convinced they are trying to direct traffic to apps that use their Ads network under the guise of such vaguely-about-security messages.
