As a San Franciscan, I am so happy to see this. SF needs negative feedback on the poor choices it makes, and so far the tech boom has somewhat obscured the consequences.
I am hardly a fan of Gerard but this is a well written summary of the guidance.
The only thing I would add to clarify money transmission as "transmitting value that substitutes for currency" is that exchanging funds for goods (normal commerce e.g. buying a coffee with credit card / cash / apple pay / stablecoin) is probably not considered money transmission. But I'm not your lawyer.
One-star reviews are the best signal I can find for product quality. They will let you know if there is a repeatable issue with trustworthy incentives. If there are more 2 star reviews than 1 star reviews and there is no pattern in the 1 star reviews, that's a great sign.
Stories like these make me think there is a real need for electronic devices made entirely in the US (or your preferred trusted country).
Products like the Yubikey are apparently made in the US / Sweden, but I wonder how many components are actually made elsewhere and just assembled in these countries. Are there any good examples of consumer devices actually made entirely in the US down to the microchip?
