While this kind of behavior makes you question it, personally I understand it. I think the people who get their refund and still "crying" about the state of the game are doing this because of their disappointment. It seems they wanted the game to succeed and be among the great ones, so even if they had fun with it or if they got their money back, they may still feel bothered by it not meeting up to their expectations. Because they just wanted it to be better. In some ways its similar to cheer for a Football team in the off-season because they bought great players, and even though you didnt actually pay for them you are hyped to see them win the league, yet after few months they get destroyed and you are very angry about the whole situation.
I, personally will not take my complaints and whining to such degree if i got my refunds, it will still bother me slightly but thats just me, however other people like the user you responded to may still have that bitter taste in their mouth.
Thats my interpretation on this.
