"Your honour, I thought he might object to being shot, but after I did it, he never ever raised the question! If that's not silent agreement, I don't know what is!"
If a project developer, active user, or someone else with genuine stake in the project community complained, we'd pay attention ... but nobody has, despite the numerous venues available to them to do so. Your honour.
It's not our responsibility to account for, be accountable to, or be concerned for outliers.
I'm a project developer (Django + other things), IRC has been blocked at my last two places of work and I've often used mibbit, which I found to be an excellent client - better than many desktop clients in fact. Please consider this a complaint.
Then if the Django IRC channel has banned Mibbit, I suggest you speak with them -- assuming Freenode decides that expending volunteer services to support a commercial service is a worthwhile venture.
Otherwise, there's the freenode web IRC interface.
You just said you would pay attention if someone "with a genuine stake in the project community complained". And then someone did, and you brushed him off.
"Our channels". As I've said before, we've been forced to regularly ban Mibbit on our channels (as in, software projects with which I am involved). I simply don't represent freenode, or django, or web developers in general.
[edit]
I see Mibbit fans are downvoting any negative comments en masse, not to mention the vitriolic dialog with freenode staffers on IRC. Yeesh.
