I hate this argument. Yeah, IRC is open and there are tons of clients for it, but Slack is the only one that I've used that a) retains history without you having to think about it, and b) is actually really really REALLY nice to use.
That said, if all you need is simple team communication, IRC works great
Slack's clients also have persistence, as in shows the most recent history of communication.
Not everyone uses screen/tmux with irc (though they should).
