I see the point, but a) Canon make much more than cameras or photo-related, unlike say Nikon, and a bigger market means more players overall. There’s as many manufacturers making pro-level kit now as I recall from the 1980s, and somebody’s buying the stuff to drive the investment - I think.

I also hear you on the point about transitioning to newer tools, but would suggest that photography has always required significant personal investment in money and time, and one must sweat the assets as they say, to make them pay off. Some technologies seem more convenient, like digital, but can end up by funnelling all the effort onto fewer people, instead of throwing the film over the fence to other professionals who could do a much better and faster job of developing and printing.

Sometimes of course, the sweat and toil is all part of the product - as no doubt my mate who built his own camera made from the timber of the woods near his home would tell you - but in the modern world, most people just want to see the image as soon as they can…
