Matt Finston got exactly what he had coming to him on the FITX Facebook page. At my place of employment, we wouldn't let someone talk crap about our company up and down on our company Facebook page. Bill did the right thing shooing him away. Matt obviously has his own Twitter / Facebook account and if he wants to whine constantly about a company he owns no shares in he should do it on his page.
And Matt IS a critic. I could care less what he thinks. Freddy Got Fingered is the greatest film ever made and critics hate it.
