It's not about entertainment demands, its about failing to commit when you have a cast entirely willing to help you get involved, and then claiming 'boredom' when you hadn't been engaged to begin with, not only wasting their time but everyone else's too. Just a huge slap to the face of everyone who bothered to read what you did manage to bring to the table. 

But seeing as this is a pretty big deal for some people, guess I won't do it again.

EDIT - And just so there's no confusion, its not the fact they wanted to leave, its the reason behind it. That's my real problem, ignoring the resources you have at your disposal and suggestions people offered just to say 'nah' and not try to rekindle the fires at all. It's not cool.
