Also the good old phishing emails/links. So many people are simply unaware when a website is pretending to look like an app/floating window. Even younger people who you'd hope know better are falling for it today. I work on a PC game and players (mostly young adults) are constantly getting their accounts compromised by the same phishing sites that pop up monthly.

AI voice and video cloning scams are also only going to increase. Why would scammers need to get people to install random APKs when they can just impersonate a family member and tell them what to give directly?

To me it seems very much like the classic "think of the children" type argument. It's not going to really fix anything in the end but it will benefit Google.
