FDroid clearly didn't detect how the app queries contacts from an external server. Neither does FDroid check if the app uses newer better APIs to conduct its activity.

Why would google care about the email client people use. They may care about the email provider people use, because that‘s where all data passes through. But I‘m fairly certain that for all they care, you could have your mail printed or view them as an expressive modern dance piece.

Because the "client" is where advertising can be most easily inserted to monetize that user.

But they don’t. Or does the default mail client on Android come with built-in advertisement?

Personally I don't know, as I use K-9 Mail from F-Droid.

But from the viewpoint of an advertising company, keeping the option open to insert ads, even if they may not be doing so at this time, is in their best interests.

I trust FDroid more than I trush Google.

I'd rather not trust either. Right now both can impersonate any developer out there and nobody would be any wiser.

true. but fdroid has the better track record.

This means nothing.
