I have not read such claims. What I have read are individual small-scale customers approaching base layer producers like E-Ink and being disappointed after expecting assistance in getting their product ideas to market. That's analogous to a 10,000 unit/month or less customer approaching say a liquid crystal supplier, or AU Optronics and expecting any form of support or assistance. The outcome of such an interaction is pretty much guaranteed. Even the top tier distributors won't talk to you unless you're expected to order at least 100,000 units a year. Anything less and you go through the normal OEM development path of which there's tonnes of partners. You do what everybody else who has a display product idea does, which is go to SID or maybe just CES, and talk to OEM vendors. If you've got an E-Ink product idea, probably somebody like Netronix would be your OEM partner but even they probably won't talk to you unless you're putting down big NRE. That's just how it is. Volume drives the products. You can't have small volume and cheap unless you're reusing some component that someone else has driven the volume for. That's just as true in the display industry as it is in any other tech industry, eg: LCDs, OLEDs, CPUs, memory, sensors, even passives like resistors and capacitors!
