You and I are human beings with our own opinions. Business relies on our good opinions to make money. They already got my money, so maybe my opinion doesn't matter, but if they want to get MORE people to give them their money...
Zaps were invented as a way for people to send lightning bitcoin to an event as a value offering. Since OPA isn't an open source protocol, I don't think "zaps" fit the medium. Maybe it's just a negative reaction to that word.
By fragmentation, I mean that only certain wallets will work with these zaps, whereas the basic lightning invoice will work with ALL lightning wallets, regardless of implementation. Furthermore, the appropriation of "zaps" outside of nostr confuses their initial intent or meaning. Podcasting 2.0 had developed the "boost" over a year ago allowing people to send lightning payments through podcast apps. At first I thought that was cool, but now I don't know how cool the attempted marketing is. Next year we're going to have pumps? Then shouts, hits, bumps.
