Lego And You
They discontinued the BIONICLE sets, despite the fans' protests. Why? Because BIONICLE was slipping and they wanted something new. They wanted to get their sales back up.
They changed their policy, despite the fans' protests. Why? Legal issues mostly, presumably to avoid any sort of trouble or incidents that could potentially happen in the future.
Yes, it's true that LEGO has worked with the fans many times in the past. Heck, our own admin is currently an ambassador to LEGO. There have been exclusive sets designed by fans and such, but what you have to realize is that this isn't their primary function. Their primary function is to succeed and thrive as a company, whatever it takes.
Just something to consider before acting like everything LEGO has done that you dislike is some sort of a personal attack on the fans.
