I hope one day there will be a good Google Wallet alternative. I’ve got a Pixel phone with GrapheneOS, and Google Wallet does not work because Google doesn’t trust it. It would be great to get something in it’s place.

If Apple really care Asahi wouldn’t be reversed engineered, and instead would be implementing from docs.

No. Apple cares as much about FOSS as they care about privacy. They only care when it suits them.
