Or they disagree with all of your posts, including the parts where you say that 6652 might not always be the a good idea. Not because of the message, but because of the phrasing:
The thing is that this is not helpful advice. There are cases when 6652 is preferable, sure. The above makes it seem like it is better any time you're stuck with a haste value between 3043 and 13163. As has been shown, that's not true: if you are at 4k haste, staying at 4k haste is better than going for 6652. Aside from on heroic Norushen (which is arguably the easiest heroic mode anyway), you'll probably find that staying at 5k is also preferable to going for 6652. It is worth going for if you happen to land just below it even when reforging out of haste but can't gem to reach 13k, which probably doesn't apply to a whole lot of people. Those people are arguably few enough and the difference small enough that 6652 really isn't worth ever mentioning.
