Personally if I had had time and money I would have been in MC.
I've seen images, videos, and it's spectacular with new ideas. I understand that a lot of Chess player are quite shy or so genuine people and perhaps they can't like this kind of event, but that does not mean that it can appeal to other people. If you do not like just do not go.
Yes there's a critical point, the sandbagger. I think with intelligent rules or different rates they will be able to avoid this.
It's a dim new trend out in bloggy-land to call anyone who criticizes anything a "hater."
Think Donald Trump would be a bad president? You're a hater.
Think Hillary Clinton is not trustworthy? You're a hater.
Think Millionaire Chess made huge errors with sandbaggers in their last tournament? You're a hater.
There is good criticism, bad criticism, and plenty in between. But calling any of it "hate" is just a lazy and insulting attempt to chill conversation by attacking people as intolerant.
The best way to deal with it is to totally ignore the person saying it, since they are patently ignorant and have nothing else to say.
In this particular case, the poster put up a long thread on Millionaire Chess 3 that revealed him/her as a shill for the company, because he/she announced information about the tournament that has not been publicized anywhere else. So the call to ignore is even stronger.
