they don't sell them to people who don't know how to use them. with the exception of knives. but unlike technology, people do know how to use knives without getting hurt. they can easily see that chainsaws are dangerous. they need a drivers license for a car, and they can't get opiates without a prescription.
none of these controls are available for apps, and yet, because they don't know how to use phones/apps safely, because they can't tell the difference between an app that is save, and one that isn't, they risk their livelihood because they fell for a scam. they are not going to install those apps by themselves. they will ask the techshop around the corner to do it for them, and the scammers give the techguy a cut for installing that app that steals your money.
the problem is of course lack of education, but education doesn't have a quick fix. in the meantime many peoples lives will be ruined.
By contrast, they think the 4 ton death machines are a really cool way to impress girls and that's what they're used for. Similar in Europe, by the way.
Not that there's any shortage of people who think guns are a cool way to impress girls.
Even if we are restricting installing apps, there are less heavy handed measures. By enabling .apk installs only via developer options/command line/adb in a way that the average user will never be able to figure out, for example. Sprinkle a few warning pages with scary red lettering and it's fine. Grandma will never figure out how to run adb commands on Gentoo.
There is a tradeoff between liberty and security. You can never guarantee security; the Google rules in the article won't ensure it either, as Google has been shown to simply not care about scam/malware apps published onto its own app store anyway. The whole security angle is a misdirection. The whole move is about control.
