Didn't know that. Ridiculous indeed. I mean, it's one thing with the curved back ones (I kind of get that it would be a bit awkward), but these new ones are similar in shape to their $5000 standalone monitor, which supports both their stand and VESA mounts, I believe.
The $5000 standalone monitor does not have a VESA mount, you have to buy an adaptor.
It's ridiculous, because a VESA mount is literally just 4 holes with M4 thread.
With Apple, everything is secondary to profit.
(Also, 2m power cable is a bit short for an articulating monitor arm...)
