I have been a big fan of the Mozilla Public License 2.0 [1]. I find it is the best combination of "if you use this and improve or modify, those changes need to go to the original code" while not restricting overall usage.

IMO there really isn't anything you can do to prevent people from making a product out of your work if it is open source, but what you can do is make sure that if someone makes improvements to your work, those improvements need to be publicly available under the MPL2.0 license as well.

This has the effect that if someone wants to make a product by just 'adding one line' that line needs to be published and you could add it upstream, making it publicly available again(thus making it harder to make a product solely from your code).

Isn't that the same as lgpl?
