I'm just not buying their explanation, that's just an excuse. Why? Well my wifes grandmother (80ish woman living alone) showed us something on her phone a few months ago: Big red flashing text that her phone was somehow infected and she urgently needs to call x and do y. Now how did this scam get full screen access to her phone? She installed a card game app from the Google Play Store, which showed this scam as an ad. And the little logo in the bottom gave away one more detail: The ad was delivered via Google. IMHO Google just wants to ensure Android stays under their control and they can make lots of money with it. They don't care if average Joe gets scamed (they even get a cut) and the measures they pretend to protect average Joe just don't work.

P.S.: Some speciation from my side: That ad was probably even targeted to less techsavy people power by Google.
