As a long time gamer and a long time consumer of gaming products large and small, it's really a simple situation:
Embrace the suck and play by whatever guidelines and get whatever benefits come from it, or move onto a new system of your own design and work on building up a community. Does it suck? I'm sure, but we're decades past gaming being a niche industry at Gygax's table. Why is anyone surprised Hasbro is trying to get more money from WotC? They're doing the same with MtG. Why are people surprised that a corporation Corporations?
Businesses adapt, and I think if 3PP decide this OGL is egregious, I'm sure some other publisher would be able and happy to publish your home system if you can't get in with, say, Pathfinder.
OR is your issue that you won't have a built-in audience for 'the World's Largest Roleplaying Game'? Let's just be honest about it because there are plenty of designers out there who put out new work and have for decades with their own system, etc.
