To pose a counter-argument: should all open-source projects avoid jQuery? For many projects, it's a huge time saver, doesn't cause issues, and plenty of people like it. I totally agree that if you want more people to use your code, you should consider the implications of tools like these, but often the tradeoff is worth it.

You don't have to use my code, so I'm going to use the tools that I think give the best results.
