I wouldn't call it hate, more frustration that is expressed in a negative way. Many of us have spent tons of money on this game, and also gotten tons of fun out of it. But when bugs interrupt the fun people get frustrated, especially when they don't get fixed.
I do agree that a more positive approach is better and gives more motivation for the team to get things fixed, but leaving feedback in the written form on internet can be misinterpreted, someone might have meant something nice but whoever read it might have taken it as something negative. Like this reply, I mean well and no harm, but someone who reads it might see it as something negative.
With that said, I wish you a festive winter season with lots of laughs and happiness!
