I'm sorry if I sound like an art snob but he looks to just be milking the common view that "modern art is dumb/stupid/no talent/i'm not cool enough" for no reason. He just seems to be whining for whining's sake. See his other articles about "giving art another chance". He's not looking to think or allow for expression in any form. He just wants to whine that people like to think abstractly and he thinks it's dumb. To each is own.
