Note retroswap supports physical cash transactions. I’ve never used it but It looks like you’ll need some Monero as a security deposit, and of course there’s is random chance involved in finding a willing seller to accept the gift card. If you pay with the card, remember whoever originally bought it is theoretically traceable by visa.
There are also many sites that will buy gift cards, at a loss. You may be able to use one of them to turn it into fiat.
Also a pawn shop may give you cash for a gift card, idk.

The issue I have with things like FloC and the topics API are that they are attempts to keep the cash flowing at Google before disabling 3rd party cookies, when it seems obvious that the time to disable 3rd party cookies is now.
As a life360 user, I really don’t know how any reasonable person in the last 10 years could sign up and not know they’re selling location data. It’s a free service primarily designed to track your location. I didn’t read the terms, I just assumed it to be true.
