It's easy to run unsigned binaries/app packages on macOS: right click on the .app, hold down Option, then click Open and confirm the warning.
The closest Apple comes to this capability is achieved via device Supervision and MDM, which might be comfortable for some of us here in this forum but obviously isn’t practical beyond more technical circles.
Baddies keep ruining all the fun for the rest of us.
IMHO the blame rather lies with our politicians who are unwilling to take the steps necessary to cut the baddies off from the Internet. Let's see just how fast India, Pakistan, Turkey and other scammer hotspots clean up their act when the US+EU threaten to cut them off from the Internet and SS7 unless the scam callcenters are closed down for good... the amount of corruption regularly exposed by scambaiters on Youtube is insane. Billions of dollars of damages each year [1] from that bullshit and our politicians don't. fucking. care.

You don't need the whole world. The Western world is enough - no Internet and phone service (both easily enforced by requiring providers to reject ASNs / phone country codes) means a lot of lost business for an affected country.
> Pressuring India is hard enough, try Myanmar, a place that doesn’t get along with the West at all and is already a hotspot for phone scams targeting Chinese speakers.
Honestly, that's China's problem to solve.
> So I’m all for pressuring India to crack down on scammers, but I don’t see how that would reduce the desire to tighten software controls on PCs.
When software vendors don't have to gate more and more features behind more and more obnoxious bullshit simply to whack-a-mole scammers, they won't.
