You're always going to end up with shitty solutions to some problems. Making open-source projects good requires several people to devote their lives to it. Very few projects achieve critical mass and all the other ones languish in obscurity. There's always going to be way more failed projects than successful ones. If you consider their existence a huge problem in open-source then it seems the only fix would be to stop trying. I don't think crappy solutions dissuade people from making better ones, if anything all they do is cause people to think: "These guys obviously got nowhere with this project and I don't see what I'm going to do better." But given the amount of duplication in open-source I don't think people really even think that either. It's just that they attempt to make a better version and fail leaving the world with another shitty project. Or, in rare cases they actually succeed and we do wind up with something great. But we wouldn't ever get there if we didn't make 10 of those "shitty solutions" along the way.
