Until they recently shut it down (boooooo), it was possible to bridge a company Slack channel into IRC and vice versa.

My Discord <-> IRC <-> Slack <-> Matrix bridge with Matterbridge [0] still works as of today, I didn't notice anything being shut down.

Slack’s own IRC bridge was quite terrible and had been for years. It had multiple unimplemented features and multiple bad bugs. Evidently they decided they had done enough embracing and extending, and so rather than fixing it it was time to extinguish.
