The status quo most software devs believe about software is:
I can do whatever I wantIn reality, software isn't like this anymore. You, as a dev, gotta comply with various regulations and local laws if you intend to distribute software. Sure, most software in the app stores is still unregulated, but think of medical software (HIPAA or FDA in the US, MDR in the EU) or all software dealing with personal data (GDPR in EU), gambling (most countries), AI stuff (AI Act in EU), copyright (most countries) etc.
This is simply Alphabet (the company) having to comply with new regulation. In some way, this sucks for users and for devs, in other ways, it helps to protect users of (shitty) software.
And if you think about it, software seems to be the only thing you can sell without thinking for one second about regulations most of the time. It's kinda odd.
What's the possible harm? Malicious wallet app stealing users crypto coins for example.
Google Pay doesn't hold/process crypto, crypto wallets don't allow paying with payment terminals (nfc pay, tap to pay, etc).
My workaround is Garmin Pay on my wrist. Works fully offline and I have it always handy.
