If I worte a game, I sure wouldn't be happy with just anyone using my work to base their own products and making money off of it. Even if you discount the money, there are all the bad products that can drag your work down with them.
But bear in mind, even without the OGL licence someone can legally use the rules you wrote for their own product, and not pay you a penny let alone acknowledge you as the author. Legally all Mongoose have really done is bought the rights to use Glorantha, and the RuneQuest name - I doubt they have bought the rights to the RuneQuest system because legally no such rights exist. (It is possible they have bought the rights to the original copyrighted text however, but only they or the original copyright owners can answer that).
According to the word of the law, anyone here can go pick up the RQ II rulebook (just using this one as an example, pick any RPG book you want), remove all trademark references (including the name) and anything that would make your work a derivative work (so basically any words including spell names and creatures that the authors of RQ II invented), rewrite it in their own words (note that tables, however, are copyrightable) and publish it. According to the word of the law you are okay to do that.
Of course, legal matters tend to settled by who has the most money for a lawyer and not the law itself nowadays, so good luck defending yourself in court against Hasbro when you rip off D&D 3.5 without using the OGL
All a copy of the OGL really does is encourage people to use your rules, not give them permission (they don't need it due to the rules themselves not being copyrightable) and the ability to copy text verbatim, in order to harvest support for your core book. The OGL also forces those publishers that choose to use it to place the all-important acknowledgement text of your choice in section 15 - truth be told, the OGL is as restrictive as it is enabling as by using it you are voluntarily binding yourself to it while by simply rewriting someone elses rules you can get away with a little more.
The important bit at the moment is the logo licence, which is seperate to the OGL - this means the third party publishers get to indicate compatibility without being sued over trademark infringement. Thats what really gets the ball rolling - there's no point me writing a RQ OGL supplement if people can't see on the cover which game it is for. After a while once gamers understand what the heck RuneQuest rules are, the logo becomes far less important - I predict that within 18 months we'll see the first standalone game based upon RuneQuest rules without the logo on the cover and the only mention being in the OGL section 15 at the back.
