I hate to use the word "hacker"... I think that gives them credit for too much skill.
I lean towards believing it was someone who was just trying to stir up trouble given that it's been my experience that edition hate has been kind of one-sided... I hear a lot of hate towards 4E, but I don't hear much hate towards 3E even among those who greatly prefer 4E and have no interest in ever playing 3E again.
Having a spike of "Love 4E" coinciding with "Hate 3E" just seems inconsistent with this.
I will point out that most of the '3e Hate' has been ad hominem - insults against the players of the older edition, rather than the system - take a look around, there has been a
lot of it. From my perspective (admittedly biased by my preference for 3e) attacks against 4e have largely been against either the system itself or the GSL, less frequently against the players.
All too often, a comment about why someone likes 3e or, more often, dislikes/hates 4e is followed by someone insulting the 3e player for stating his preference. In part this is because some of the 4e group is feeling defensive, and is falling back on the tried and true primate defense of flinging poo.
Even this thread has had more than its share.
Me, I have had my fill of 4e without ever playing a single game, largely because I
hate the GSL. I do not like the rules, feeling them too gamist, but it is my dislike for the GSL that is the controlling factor. Otherwise my feelings would be sort of negative-neutral.
Conversely, I like 3e, but
love the OGL - I consider it one of the best ideas in gaming since the invention of polyhedral dice. How I would feel if WotC had kept the OGL in place when changing editions.... I don't know - as I said, the rules don't attract me, but there are lots of games out there that I don't much like, and therefor say nothing about.
The result is my own feeling of defensiveness, that WotC, on some level, betrayed the good will that I had invested in them as a result of the OGL.
It is unlikely that insulting either me or my preferred game will cause me to switch preferences.
The Auld Grump, now pardon me, I need to go find some poo to fling....
