Did I write "I don't like"? The "lazy" is the problem, but then yes, I'm free to think that I don't want specific people to use stuff that required effort from my side (see the classic discussion of OSS being user by corporations without giving back anything, I can understand those that feel resentment).
If you're disgusted at the prospect of people you don't like using and extending your code, then open source is not for you.
