Sounds like self-censorship in dystopia full of secret laws. I'm glad Google isn't running a country.
Apple says that their virtual card numbers protect your privacy because they're untraceable. Ok, but that also means that your using Apple pay is mostly indistinguishable from credit card fraud.
But, you ask, does Google really have to worry that much about fraud? Do people really phish known-good Google accounts, add a stolen card, and then buy a whole bunch of ads?
Well.... yeah. That's actually one of the primary uses for stolen credit cards.
