I don't think it's so clearly a terrible move. In some respects, IRCcloud is like a metastasized cancer, growing in user count and connecting to every ircd, then moving all that communications traffic through a central service. That's antithetical to the idea of self-hosted, private chat networks which irc allows for. Allowing irccloud makes me think "should have just used discord".
Edit: Okay, on reflection, I was being harsh and... incurious, maybe hyperbolic. Being able to freely connect to a service with whatever client you want is important, maybe especially so for Freenode. I'm still concerned with IRCcloud's effect on the "ecosystem", if you will.
