I really don't understand what people think they will gain by deliberately trashing other companies. It is one thing to point out problems but the degree of vindictiveness and glee which is being displayed in some of the postings at other people misfortune is really distasteful and doesn't help sort out the issues. "Childish" is the best description I can use for some of the postings.
The postings in some of these threads doesn't help Bitcoin either as it will scare off potential investors and gives the opponents lots of ammunition with which to go to the regulators and try to ban commercial Bitcoin transactions. This sort of behaviour will prevent wider adoption and a future rise in the value of Bitcoin.
The Bitcoin world is big enough for people to have different opinions, just live and let live, it isn't big enough for public religious jihads being launched at different members of the community.
You don't burn down the entire tower block because you don't like your neighbour.
