Because there are people out there they claim your work as theirs (some guys here might remember old storys from razor and why yener left (but in fact he apologized more than once after he realized he has done stupid things (and in my opinion he is reprieved for all that stuff he has shared to the community, kids do stupid things when they are young))).

But i don't bother about source codes. If people want to share it (opensource) then they will do it, when not, then not. And if a source is in the internet once, it will be forever in the internet and you can't do anything about it. It's irreversible. There is always at least one guy that grab the source and spread it. For whatever reasons.

Ask CocaCola why they not publish ingredients and preparation of their drink.
