Yeah, The Dis are running a business, and this forum does not exactly run co-linear to their interests. Without a Ryan helping out for the love of it, a noisy, opinionated, forum can be a decidedly unnecessary risk for a business.
Social media systems like Reddit and ******* aren't really good fits for this kind of community either, since someone always 'owns' the channel, and if they lose interest or otherwise change focus, the channels tend to rot. Reddit in particular can be bad for that.
I'd personally spin up a forum site for people to use if I didn't have a good idea how much time and money that would cost me, and for that reason, I'm not going to criticize the Dis admins, even though I may not personally be overjoyed at what has just gone down!
Still, I'm honestly more salty about DME, so there's that.
[edit] edited to clarify which part of the quote I actually meant to quote.
