You may have misunderstood this. If the cc/plugin etc is on this forum, then it has to be open source. If it is not on this forum, it is does not have to be open source, and if you used the code it would essentially be stealing the code.
Just add:
Noone is forcing you to spend your time or energy developing for this community. Don't have anything else to learn? Don't have fun doing this anymore? Tired of not being appreciated? Don't have time? Then go outside and do what ever else will allow you to continue learning, having fun, feel appreciated, and be released from any obligation you feel you have to a cyber community.
You want me to think of the consequences of my opinion on these matters. Well, I've never been one to suck up to get what I want, so I don't really have anything to offer the devs except my gratitude and sometimes donations. Then it becomes clear that for many developers, the "consumers", the community, are looked down upon like a flea on a horse's ass. Well at that point I just need to make it clear if you decide to leave, that I'll miss you just about as much as you'll miss me.
