CalArts has nothing to do with that, you are being dense if you actualy believe on the memes. Its even more stupd because the cartoons that /co/ complain that are "CalArts style" are mostly not even done by CalArts grads: SU - not made by CA students and Sugar actualy goes on her way to contract people with no previous experience in animation/Gumball - Made on Europe/NuPPG - Made mostly by newcomers that never went to CalArts because CN said that they wanted "new modern blood".
First, the single most important thing is budget. You seriously believe that the suits selecting determined shows to follow trends is fault of the school, and not of the people who are doing the selection to begin with.
Seriously, you are an idiot.
