A lot of the decline was due to people being driven away, directly or indirectly, by tyrannical ops.
A given channel, or even entire networks, would often start out pretty free. Dissenting discussion and arguments were allowed, if not encouraged. Users could hold and share their own beliefs without fear of repercussion. It was generally a fun experience. The channel or network would see growth.
But as the community became larger and more established, certain users would often end up becoming ops, and they'd start to enforce their own beliefs upon the entire community. People would start getting kicked or banned unnecessarily for very minor "violations", which most often involved just holding a different opinion than an op.
These kicked or banned users wouldn't come back, those users who liked them would have less incentive to return, and eventually there'd be more people getting booted or leaving than there would be new people coming and returning. The channel withers. If this happens with enough channels, the network withers. As networks wither, IRC itself withers.
I always thought major reason for the decline was all the other alternatives coming up back then (msn messenger and the likes) and more recently things that aren't really an alternative but steal time anyway (facebook and the likes) ?
I agree here, my friends weren't affected by ops (we were all ops in our own channels) - they moved to MSN and gave up on IRC. Then MSN was dropped and they moved to facebook/google chat, and now it's almost like IRC was by using group chats in whatsapp, but without meeting any new people.
