this is, I think, the money shot to my lengthy ramble elsewhere. Digital photography is not a particularly good business to be in, and Kodak had nothing left once you stripped away the film business and the ancillary photopaper/chemical business.
If you're going to do it, you want to be in the pro market, you want to be selling the body, you want an extensive first-party library and, ideally, minimal competition from external third-parties (Sigma, Tamron, etc) selling into your system.
Kodak had none of that, their only DSLR experience was building "digital conversions" of Nikon bodies (using nikon lenses) and they would have been starting from scratch.
Fuji also got really lucky that Japan fucking loves cameras, especially film cameras. Fuji has NEVER given a shit about the world outside japan, other than selling freighter-loads of color negative film (disposable cameras are still extremely popular in the developing world), they give zero shits about marketing their cameras or instant film or anything else outside the Japanese market. Their camera gear (35mm, MF, and LF) has always been top-notch and it just has zero market penetration in the US because they never bothered to market it. It's also routine to have fuji stuff (Astia, FP-100C45, FP-100C, etc) discontinued with like a week of notice to japan, and zero notice to the rest of the world, they have extremely poor organizational communication because they only give a shit about japan. But they never had to, because Japan has had a love affair with photography for 70 years now.
When you look at cameras like the Fuji X-series... those are cameras designed for the Japanese domestic market, cause they still love rangefinders. So is the Pentax Q series... americans don't get it, shitty p+s sensor, why would I buy it? you're not meant to, it's a cute little camera for japanese housewives, they just let us buy it too... sometimes.
