I think some of those questions are problematic:
1,2,etc) I think photographers heavily invested into Canon equipment deserve to see be treated as valued customer, e.g. see Canon's roadmap, but it's borderline intruding into Canon internal policies. E.g. Canon doesn't owe it to anyone to release a 36MP camera, esp if management thinks there's no money in it.
This is clearer in question #6: Canon doesn't have to explain it's customers how it's going to stay profitable.
4) "Retro good looks"? This is what people judge a camera manufacturer by?
7) What apps would one want to use a DSLR for? Calendar? Waze? Chess?
Phones are multi-function devices, serving as phones, PDOs, cameras, game machines, etc. Cameras aren't. I can see some benefit in the ability to program the camera, e.g. ML, but I don't see it stretched as far as smartphones.
