Canon has been very responsive to what customers want. It just takes a while.
For example:
1. Customers demanded better wide angle glass from Canon. Canon delivered a ton of them: 16-35mm f4 IS, 16-35mm III, 11-24mm. Went from a lack of them to the best choices on the market.
2. People wanted more DR. Didn't go to first place but Canon responded and now they are only slightly behind the Sony sensors (good 'nough).
3. People wanted a mirrorless option. At first they were mediocre but now the M5/M6 are great if a bit too pricey for what they are. They'll probably continue to get better and better.
Another good example is the 5d3...people demanded better AF and whined and complained that the 5d2's AF sucked. Well, the 5d got basically the 1dx system.
Complain loudly enough, give feedback when you buy new cameras from Canon, etc, and they'll listen. Eventually. They have to.
Also Canon hasn't been pricing the new glass nearly as crazy as Nikon has.
I doubt we'll get an affordable 600mm 5.6 though. But I could see a 500mm 5.6 that is similar to the Nikon one.
