As TFA does not mention it, and I don't see any top-level comments discussing it, this is a continued rollout of a "feature" first piloted in Brazil, Indonesia, Singapore, and Thailand. See:

Of course, HN reaction has always been skeptical about this including in earlier news. But the reporting on it, and the countries in which it is piloted in, seems to me to involve government/banking industry cooperation with or pressure on Google to combat cyber fraud. These polities are prime targets for Android cyber fraud of this sort due to Android penetration, and seemingly (to me) also cultural proximity to scam operators, and tech-illiteracy among the vulnerable demographic. (And anticipating a reply I got from a previous article on my comment on this feature---no, it's just not feasible to comprehensively educate retirees against evolving tactics by scam operators and expect that to be a sufficient sole countermeasure.)
There is no doubt that sideloading by uninformed users can be used as a backdoor.
It's also not a surprise that banks/industry that's accountable to recover the losses for tricked customers is looking to someone else to solve it for them.
However, if this was "piloted", do we have the numbers of how much has it decreased the number of scams or their impact?
I wouldn't go as far as to say that it is impossible to "educate the public", but it is indeed extremely hard. But click-through pop-ups have succeeded when?
Yeah for every HN user complaining about it there are hundreds of people sideloading apps (not realizing what they're doing - under promise of loans or other advantages) and then getting their phone ransomed
I know in some people's eyes saying this will make me a Google shill but this reminds me of the manifest v3 thing. What makes it to the top of HN is mostly clickbait a las "Google is cracking down on ad blockers" or in this case "Google is preventing side loading". These articles don't link to primary sources (Google) and they (intentionally?) miss all nuance.
