Unless you have carefully documented how much of your training and education and informal contacts also went into that thing you made, and carefully ceded the correct portion of your copy control to those contributors, then you are whistling up the wrong tree and barking past the cemetary.
Yes, you built it, and you should be proud of it, but to claim that no one gets to use any of what you built when they build their own improvements is to pretend that you built it entirely de novo; a virgin idea, to borrow a phrase.
I think not, to borrow yet another.
I wonder how many borrowed phrases you have in your own post. Did you invent all those words yourself, the grammar, the fonts, website, and internet which you used to post and we used to read?
