There have been past instances of some company claiming they're now accepting bitcoin/crypto, and when going through the PoS process, you had to either log into coinbase and pay through them, or connect your crypto wallet via some metamask BS...no option to just show an invoice address and amount (or lightning invoice) and pay via wallet of our choice like we're all used to.

Theres the interoperable/sovereign way to do it, and there's the KYC/cucked way to do it.
