That is sad... What a great use of social media! One of the curses that it's brought out is the ability to attack and complain far more effectively than in the before times (1990's!) People have always liked to complain and they always will. Just imagine when they die and are in heaven, they would find something to complain about there too...
A lot of times it's just better to let things slide and not make a big deal out of things, otherwise you stir up the hornet's nest. Maybe it's the wisdom of aging! Not to sweat the little things anymore.
It's definitely a mob mentality whether it is right or wrong. We have seen lately that even with scientific facts people believe what they want to believe.
