Because stink levels need to be MASSIVE for Riot to listen anymore. They got their reputation while they were a small time company. Now that they are big and famous, well, it's their game and they will do with it as they see fit.
This isn't exactly a new sentiment either. Communication is at an all time low, and frankly the amount of stink that needs to be generated before ANYTHING happens is beyond rediculous.
Example - Take note of the OP containing a large quantity of threads, and consider that these are only the ones that got enough attention to merit linking.
The fact that they used to be known as the "player focused company" is, well, just the past. It's been long enough that Riot is going to need to prove they want to fix communication before the player base starts believing it again. Because honestly, they haven't really implemented anything since the boards. And even then, the Boards aren't complete, and communication is actually worse than it was when we were still hobbling along on vbulletin.
tl;dr - The old level of communication simply doesn't exist anymore, and hasn't for a long time. They need to actually address the issue of communication, and not blame it on bad formatting or that they don't like what they see. Communication is a two way street, and if it's implemented as one way to a brick wall people are going to be upset.
