The "luxury goods" strategy is viable in a direct to consumer play. But does it still apply at the component level? If anything, I'd think there's an aversion to lower volume, single-source boutique parts just because of the fear of supply chain kinks. Maybe there's some marketing case to be made of "you can elevate your product's market position with expensive premium components" but that argument has a lot of moving parts when you're not the only displauy tech on the market.

I wonder if there's a non-margin factor in play. Maybe something like:

* They don't want to be in the "support" business, so by keeping the product line away from hobbyists/small players, they keep their overhead low.

* Their main concern is product secrecy and therefore will only deal with firms large enough to take NDAs and licenses seriously

* Their manufacturing capacity is finite and not easily scaled, so they couldn't actually deliver on a hypothetical millions-of-screens-per-year order.

* Some sort of brand protectionism. I see a lot of "we could probably hack and rig an E-ink display to do something outside its normal sales case" discussion. I could imagine a situation where they ended up-- in the eyes of end consumers-- responsible for the failings of such products. They never said to use their panel as a desktop monitor for playing 60fps video, but they can't stop someone from trying and then bellyaching about it to the world.

Of course, a mandatory-licensing mechanism could help escape whatever tarpit they're in.
