Hi,
Whether Squidley works for W-E or MS or gets paid by Bill doesn't bother me much.
What bothers me is that his apparent intent in posting is disingenuous. He asks rhetorical questions of us, or questions "why was the tying claim remanded?" or the like when these questions can be answered by his examination of the original sources. He obviously thinks that he's making a point, or he's hoping to make a point on the response, but he's trying to have his opponents do all the work. As you point out, he often doesn't answer direct questions while expecting answers from others.
If he wants to advance a position and back it up, fine and dandy. Healthy debate is good. Elisa-esque rhetorical questions don't add much to the conversation though.
In short, I think he's a troll and not a shill. Trolls get old fast.
My $0.02.
Cheers,
Scott.
