I believe what irks them are what they perceive as unnecessary compromises; the current poster-case for this is the sensor of the 6D2. It's known that there was better sensor tech available (5D4 and 80D), and could have been used.
I don't know if you meant me
But to be clear, I was speaking specifically to bird feeder BIF shots, something I've spent quite a lot of time on because I hang out on the patio with my wife, where we have, well, you know, feeders. Really, I wasn't pushing the 6DII here. I was saying, Olympus, Nikon, Canon, 4 fps, 6 fps, 10fps, 18fps... It really doesn't really much matter.
My preference, rather than to essentially capture video and then look for a good frame, is to spend some time understanding that, for example, when a chickadee has a peanut in its beak and doesn't bite down, that's a pretty good indication that he's going to take off. They'll look the direction of travel, so while they're facing the feeder, there's no point in clicking away if you want to catch an in-lflight shot. Or, if I keep one eye on the surroundings, and see another songbird on an approach vector, at a certain point, I know that certain birds on the feeder will fly off (while others will be unintimidated and just go to the other side of the feeder). When you shoot it (time of day), and where you position yourself is critical, too.
They behave a little more differently when they show up for the last meals of the day, as opposed to when they're more social mid-day. There are also favored types of spots where songbirds land before they go to the feeder, or queue up. Get to know them, and you can have a more natural looking shot, and also plan better.
Take a waterbird, like a groebe, heron, duck, crane, or a bird of prey like an eagle or osprey and it's the same principle. You can either try to randomly catch everything and have memory cards full of content, and maybe still even miss the best shots, or you can learn the behavior of your subjects. Doing so is not a handicap, not an advantage. Of course, there are more tools needed when the subject is 200 feet away instead of twelve.
I'm sure a sports photographer would tell you the same thing. They don't go to an event and just hold down the shutter button wherever the ball is at the camera's max FPS.
Yes, I will happily concede that some technical features may be helpful, and in some cases, will give you more usable shots. I also think that if you rely overly on them, I think the end product will suffer. But that's just my opinion, and if anyone personally needs all one of those in order to enjoy photography... have at it, and don't bother with a Canon... though I think that you'll never be happy anyways, because someone else will come up with something that you've gotta have at some point.
