The statement was "confusing" because it was a "lie". As in, people could be confused by what kenjackson said, because the words he wrote were not true.

I'm not interpreting it as an attack. It is an attack, and relatively common type of attack regularly employed by folks who dislike the GPL (as I mentioned, Microsoft once used it with regularity, but they aren't the only ones, and they've been off that particular horse for a while, I think). I'm merely calling it out. I've been involved in Open Source software long enough to have seen a lot of FUD from a lot of different angles. Sometimes it is subtle, sometimes it is obvious. This one is an old dead horse that's been beaten to a pulp, but folks still like to trot it out now and then (or roll it out in a wheelbarrow, or something).
