Whatever Dave Williams is, he's no friend of the shareholders. His private war with the board has stopped the company from getting anything done. It's all Dave, Dave, Dave. He clearly doesn't give a crap about us, only "punishing evil board members." This is sociopathic behavior. He can also put the company into receivership, after which AT&T buys the patent at auction for 5% of what it would have cost them in royalties.
On the other hand, Turrini et al are clearly crooks who I'd bet a day's pay are being back-pocket funded by the infringers.
The problem is whether we are willing to wait X more years for a fair resolution after we fire the BOD.
