It really doesn't matter if others like it or not. It's important to have as flat a frequency as possible with all monitors but they will all have their signature regardless. The important thing is not what monitors you have but that you know your monitors.
You can accomplish this by referencing your mix back and forth from higher-end home audio systems, to car systems, to cheap stereos with small speakers. It also helps if you look at the frequency response diagram for your monitors and see where you can expect significant boosts or dips in your audio.
A good example on great monitors not having to be good-sounding monitors is the Yamaha NS-10m's. Many people did not like the way that these monitors sounded but they became standard and in many setups and they still are. The reason for this is, as much as this have been said, that if your mix sounded well in the NS-10m's, that it would translate well into other systems.
You also have to keep in mind that those guys on the links that you posted are paid to say that they switched. They may have even switched in reality but I hardly doubt most people would switch out monitors that they are accustomed to. I'd say they use them to have a different monitoring system to listen to mixes but I'd doubt that they would completely replace their current monitors. (Correct me if the thought is wrong anyone)
Although the Cube design those monitors have would probably give them pretty good low-end.
