That's deflection, there's Google blocking users from installing apps and there's OP insinuating that it might be because of governments coercion but there's no evidence to support this. Scammers pay Google to show ads to install apps, that's what the governments are holding Google responsible and it won't change with blocking installing apps.

Malicious app delivery goes beyond Google ads. In Singapore, most scam app installs are from social engineering, e.g. install new app to receive payment, install new app to buy something for cheap.

I’m amazed at how gullible some people are but that’s how it is.
