That's because the people paying them have never lived in a world where micro-payments are possible, but the people who want to accept micro-payments have studied them, and see a potential. It's like before the car was invented: all the enthusiasm came from car inventors, not the general public; the people just wanted faster horses.Micro-payments enable applications that were not possible before, like trustless pay-per-view, where you pay 0.1 cent per second of video. So the excitement is understandable, I think. The execution just hasn't been all that impressive.
I think the Stroem protocol [1] will be the winner in the short term (within the next decade), enabling a form of micro-payments that are not trustless, but with so little barrier to entry for micro-payment issuers and so huge benefits (send money to anyone anywhere instantly and incredibly cheap), I think it's inevitable. But just as with Bitcoin, we have to accept that it's not what some crypto enthusiasts envisioned. With Bitcoin, many people thought some cryptographic construction would solve the double spend problem, but in the end it was brute force - proof of work - that (partially) solved it. I think the same will be the case for micro-payments. We want trustless micro-payments, of course we do, but in the end I think a promissory note-based system will be stable enough that its lack of complete trustlessness (á la Bitcoin) won't be a deal-breaker.
