Sometimes, we get lost in evaluating the products of a company, and forget about influences that affect how it can operate. As several people have mentioned, the storms etc - affecting its ability to R&D and build product. But, even with that tragedy, Canon has managed to produce a new 7D Mk2, a new 100-400 Mk2 among other lenses and gear.
I, for one at least, believe the complete package matters, and not one part (think sensor debate here) Canon has been doing the job well for me over twenty years - and if/when it fails, I'll change and shed no tears. I've still got and use often a 100-400 bought in 1999 ... and still debate upgrading to the Mk II - will wait and see it first. Shot for years with a 30D and then a 7D until just recently .... upgrading to the 5DM3 and now the 7D2 as a very effective pair.
I read a lot of problems with the 7D2, and it 'scares' me into testing and testing, and shooting it more and more, trying to find something wrong with it before the return period expires (Nov 30th) -- and every time I go out, I come back with a whole lot of sharp detailed color balanced images ... So, it confirms my personal belief that Canon builds very good equipment. But so does Nikon and Sony, and others -- no debate there.
I'm certain some of the guys on here have truly had problems with the 7D2, and a new product (no matter who builds it) will have some 'bad ones' .. which we hear more about than the good ones. But I also believe some need to learn the camera itself too, and figure out what causes the issues. AF system, hmmm, a dang nice one, but different, so it takes time to figure out exactly what it does best, and how - AND, equally, how the AF set up interacts with other auto-features. It takes time ... and I had a tough time with its AF at first, and still am confused at times, and look at a shot and say "Hmmm, what happened here?."
It's a great camera - it is what it is tho', and has its limits just like any other camera / lens technology. In fact, it performs better than I anticipated - which makes me happy. Maybe I'm just one of he lucky ones, that got a good copy - no issues. At first, shot a lot of deletes (and worried), now get a lot of keepers. It's just that curve happens with all new equipment.
I read a lot of real detailed 'Canon nit-picking' on here, and tech debate that ends up evaluating extremely minor differences or discrepancies. Most of which don't matter much in the real world of photography, but gives folks something to complain about - or often expresses extensive tech knowledge most folks don't have, need or care about in the workflow. The image and print speaks for itself - and finding a null detail at the micron level ?? Well, it irrelevant usually.
Canon does what Canon does - whether we like it or not - and if some other company suits the need better, go buy it, instead of complaining about Canon - mainly, because it does no good and wastes time.
So, does Canon really deserve this? [The complaints?] No, I think not ... not really.
