Who's this mythical 'everyone', and does it include anyone besides you?
I suppose the 'everyone' would include those users who just shoot every photo with their main subject smack in the middle of the frame. To heck with pleasing composition..
As Canon-F1 correctly points out, using the center point and recomposing is fine if you're shooting with a slow lens (f/4 or f/5.6) and/or with a distant subject, because in those cases the deep DoF will mask the focus error. But focus-recompose with a fast prime shot wide open results in back focus - that's geometry, plain and simple. The closer you can get an AF point to your subject, the better. That's one reason why the AF point spread on the 5D/5DII was unliked (it didn't help that the outer points weren't very accurate, either).

I think the mythical 'everyone' are people like me who used to make a living with a pair of the original 5D's, where center point was the only point worth using, and that method of working carried over to the 5DmkII, partly out of habit, but mostly out of necessity still. Having used the 85L+35L for 90% of my portrait work in that time, I've always able to nail focus where I want it in more than enough shots to get what I needed by focusing and recomposing. Granted, I am talking about portrait and wedding work, mostly. It only takes a little practice and finesse to figure out what works, but it's not like I ever have a bunch of back-focused shots in any given take, and it's not a problem to finding pleasing compositions at wide apertures.
Now that we are onto the 5DIII, I find myself actually changing focus points all the time, and it's been it's own small learning curve, and I focus and recompose less. That being said, my keeper rate is higher overall, regardless of focusing technique, with the 5DIII because it really is just so much better overall and I'm learning to actually trust my camera, which says a lot. (finally canon, thanks).
