Kodak managed the film and camera market about as well as they could. The mismanagement was a failure to diversify. The total digital camera market excluding cell phones, would be a fraction of Kodak's film business back in the film era. The film and camera story is a popular one but is fundamentally wrong. The shrinkage of the camera/film market was inevitable. You can look at Fujifilm who does sell cameras and basically owns the remaining film market with instax, however neither of those sustain the business they are effectively a chemical and medical manufacturer who dabbles in photography now.
Kodak on the other hand attempted to diversify to those markets in the 80s and 90s but made some terrible investments that they managed poorly. That forced them to leave those markets and double down on film just in time for the point and shoot boom of the 90s and the early digital market. Kodak was a heavy player in the digital camera market up to the cell phone era: they had the first dSLR and were the dSLR market for most of the 90s, they had the first commercially successful lines of digital point and shoots, they had the first full frame dSLR in the early 00s and jockeyed for positions 1-3 in the point and shoot market until the smart phone era. They continued to make CCD sensors for everyone during this time. Ya they missed the CMOS change over and smarthphone sensor market, but that was well after they were already in the drain.
