^ I don't see it as indicating undesirable character at all. I read the piece as more an indication that the guy knows when to cut his losses and stop allocating resources to unprofitable activity. Which to me, from a business perspective, is a sign of someone with their head screwed on straight.
I also don't grasp the logic behind the notion that once a creator shows his work -- or work-in-progress -- to the public that he is somehow bound by duty, honor, respect for his 'followers', or some other compelling consideration, to finish that work.
If Beethoven starts writing a string quartet, and posts the first movement on the internet, but then realizes that the Duke isn't going to commission it and he'd rather be writing a sonata anyway, does it really reflect badly on LvB if he abandons the quartet?
