See, I love it. I work for a mostly-remote company and before Slack we had an IM product but it was a 1:1 chat. Having an always-on chat room for the entire team, knowing other teams use the same product and I can pop into their chat room, spinning up channels for project teams, etc. It's been a huge boost to our company.
And since so many companies have settled on the same solution, when I'm working with a client I can join their Slack workspace too. That cuts down on the numerous quick phone calls and long email threads that we used to have.
Slack vs Teams vs IRC vs anything else, I don't care. It's not about the product. But my company (and most of our clients) didn't have this capability before Slack even though IRC existed for decades, so I'm going to give Slack some credit.
