This post to me sounds like someone claiming spam filters are worthless because an email got across. The relevant metric is how many scams aren’t there, not how many have managed to stay for some indeterminate amount of time.
If anything, these examples just illustrate why centralized app stores are inherently flawed, even if Apple's store is of much greater quality than Google's.
Corporate cheerleading is boring and elides that the greater issue at hand is about openness and choice vs. closeness and security. Examples such as TFA illustrate that despite corporate promises, their security is incomplete.
If I'm literally prevented from using any other kind of spam filter, you bet I'd be complaining.

Actually, you can use another kind of spam filter - your brain.
