While I think it's fair to say these sorts of applications do disrupt people and reduce their productivity, I'm certain that they help focus team efforts in a way that meetings just don't.
You can't split off 3 members of the team and have an important technical discussion during a meeting (or if you can, your project manager / meeting organizer isn't doing their job). You can't come back later and see exactly what it is you said that you'd do after a meeting. You can't tell a bot to create a bunch of tickets or what the current status of a system is.
If you find that your chat apps are not providing you with any value, maybe you're using them for stupid purposes like sharing funny pictures & this mornings cool tech blog post, or you're subscribed to the support channel, or your team is treating them like a social hang out space.
It's not that its a bad tool; its that you're using it wrong.
