I have lots of code all over the internet "rotting". Some of it was written because I actually needed it. Some because I was learning. Some to prove a point. Some to just play. There's lots of reason to write code, and lots of reasons to let it go. Now here's the thing, putting code on the internet and typing "here it is, BSD or MIT or whatever licensed" is a trivial marginal effort. Since that effort is effectively $0 for me, I do it, thinking like this:

Maybe someone will get some value of it. I don't want it, I don't care to put effort in, but hey, if someone else does: cool!

Basically, putting stuff out there is not that different from the freecycle mentality.

The place you seem to come from is that "Oh they want to make an open source project, that means they must want to be $0 vendor for my company!". Honestly, I hate that mentality. Instead of coming in and demanding I give you more effort for free, take or leave the free work I choose to do and let it be. That's not to say I am not open to suggestions or maybe even explaining or fixing things, but you have no right to expect it of me.
