I don't think anyone here constantly claims Canon does everything right. Right now, I can think three things almost everyone agrees are not great: UK pricing, ability to only partially use TCs on the 100-500mm (and some other lenses not at all), requirements for CPS membership.
Personally, I have yet to purchase any of these narrower lenses, but after seeing other people posting wonderful shots with them I definitely consider them as good value products. As far as I know, no other company is offering 400mm at under $1000 (with the additional advantage of low weight and short MFD) or 800mm under 2000 (let alone the prime under $1000).
Although I mentioned George's joke about half of people, I also heard in a psychology lecture the idea that there is a tendency for people to consider themselves to be the same as most people... For example, if I like strawberry ice-cream it's likely I will think most people also like strawberry ice-cream.
