When you write for yourself there are bugs and limitations that you know them and you may or may not put time to fix them.
But when you publish a free code for public usage, some people think just because you share your code, they paid you for it and they let themselves tell you whatever they like.
Thats why so many people don't like to post their codes and just use it privately instead of posting it for public usage.
Thats absolutely right - you will experiencing with every kind of work you will do free for public some kinds of people who are thinking they bought you.
But don't forget the lots of user, also those one who are only reading here and be very thankful for the whole work you guys are spending to keep the project alive and expand IMO to the best project you will find for all of us!
