There are plenty of legitimate grounds for criticising Matthew, but he no more made people do the things you list than pirate or the pass-through operators made people give pirate their Bitcoins.  Buying pirate debt on the basis of someone else's actions is ridiculous - you have no way of knowing whether they're just trying to inflate the price for their own benefit.  People with true inside information try to hide it from the market because sharing their inside knowledge dilutes its value.
