So, having to flip through a book you're expected to own is worse than paying money to buy the same content twice because a publisher wants a "complete" game that only contains a small percentage of new content? I don't think so. God forbid I have to flip through the PHB I already own instead of getting the combat chapter repeated, word for word, from some lazy developer.
Ah, but what happens when, say, 10-20% of the chapter is different? 30%? 50%?
Let's say I want to do a dark&grim Sword & Sorcery setting for 4e. I want to make some changes to combat to reflect the kind of world I want to model, one where there's sudden death for even the greatest of heroes, and where a horde of faceless minions can overrun the mighty. I don't need all-new combat rules; I need to tweak them in a lot of different places.
Which works better:
a) "In paragraph 3, change sentence 2 to read "Unless surrounded by three or more opponents".
b) Reprinting paragraph 3, changing the sentence as needed in the context of a full chapter on combat, with proper flavor text and examples to fit the new setting.
Multiply by a few dozen pages of rules.
Since rules can't be copyrighted, the whole VALUE of the OGL was in the ability to reuse text. Remove that, and what have you got? Damn little of worth.
If WOTC didn't want to continue the OGL, they had a chance to say so -- in August, when they said, contrary to the current facts, that they WOULD be continuing it. Changing things now makes them look as bad as people speculated they were when the OGL was first announced and "WOTC will STEAL your GAMES!" was the cry from the suspicious.
