Libera retained like 90% of the freenode channels, with maybe 5% jumping ship to other IRC networks, mostly OFTC, and 5% jumping ship to Matrix, Discord and Slack, from the posts about channels leaving freenode. Libera is also bridged to Matrix, so Matrix users can participate in Libera channels, so there's also a decent amount of people using Matrix as a glorified bouncer. Very few new communities are setting up on IRC. My impression is that until the Freenode meltdown, Discord was most common, followed by Matrix, then Slack, but the freenode disaster seems to have benefited Matrix more than Discord or Slack. That's if you look at official channels, if you look at user counts in unofficial community groups as well, Discord has to be way in the lead. The Python community discord has about as many online users as Libera in its entirety, for example.
