FreeNode doesn’t, not do many others. The unstated assumption here is that it’s easy to decentralize IRC because “run your own server”, but it’s not easy to run your own IRC server, nor to time-efficiently share how to configure IRC clients on how to connect to it using SASL.

Freenode does run services, just maybe not ones that do what you want. Slack is definitely easier to administer.

just pointing out the desired level of control is possible with an IRC server, contrary to what the comment I replied to said.
