Do you really miss the point?
There's no necessity for a different publisher.
If the implication of "more choices is good" was that "one game publisher would suffice to keep the entire roleplaying populace happy," I confess that I absolutely did miss that. It seems unintuitive to me.
Is this really so hard for you to understand?
No, it's just that I don't believe in the kind of absolute "all or nothing" language you're invoking. It's like asking if it's so hard for me to understand that the earth sits on a turtle's back -- understanding the premise is a long way from agreeing that it's true.
Real game design doesn't deal in absolutes like "you must change
next to nothing or you must change
everything." If you're making a Star Wars game, and you've discovered that Gungans and Ewoks aren't real popular, you don't assume that your audience hates everything about Star Wars aliens, and throw out Wookiees and Twi'leks and Rodians as well. You certainly don't throw out everything and make a Star Trek clone. You look at what they do like about Star Wars. And if, in the process, you find a lot of people rate Han Solo as their favorite character, you consider making smugglers a competitive mechanical choice side-by-side with Jedi.
Go ahead and make a game for those who consider Vampire fatuous and boring rubbish and Mark Rein*Hagen a hack. That might be a splendid game.
It doesn't work that way. Games are made up of individual elements, which people are capable of examining on an individual basis. That's why we have controversies like this: because people may like 80% of a given game edition but would like to see 20% changed. Or 90/10. Now, if part of someone's 20% that they'd like to see changed is something you really like, sure, you disagree. But assuming that they would be happier with another game when they like 80-90% of this one is almost certainly a failure to understand what they like about a game.
Again, think of Star Wars. If somebody says they'd like to see some stories about non-Jedi for a change, it's silly to tell them to go find another sci-fi universe to follow. Star Wars is big enough, and full of so much stuff, that someone can find lots of things to like about Star Wars and still dislike some elements. D&D is the exact same way.
(Of course, I can't help but notice that you work for the competition, not for the owners of the D&D brand!)
Ha, that would be an interesting conspiracy theory! "He's agreeing that people might not care for older wizard/fighter power dynamics, guys! He must be trying to sabotage WotC!"
No, actually, I like 4e quite a bit. And B/X, which I started with, and the Rules Compendium, and 1e, and I had a lot of fun with 2e, and 3e ultimately wasn't for me but it certainly provided some good gaming (and a Scarred Lands supplement I'm personally very proud of). I wish WotC success in their endeavors, and actually I've been pointing out how game designers can make decisions like "let's make the fighter and wizard more even at every tier of play" based on what they hear from people playing the game.
There's not actually as much vitriol in the industry as you might think. We have friends at other companies. We like playing other companies' games. I passed on a Swords & Wizardry one-shot tonight because the wife was feeling ill. I do enjoy the concept of sabotaging rivals with supportive forum posts, though. It suits the industry sense of humor.
Logic seems to have gone on holiday, and not just for you. Has someone spiked the D&D branded soda pop?
Out of respect, Ariosto? Seriously, man, it's not worth dropping the debate to that level. We're all just talking about games that we like to play.
