I am a founder of one company and work in sales. Here's where I'm coming from:

As a founder, if everyone is always DMing you, the knowledge is not shared with the team. You become the bottleneck for everything.

In sales, you end up having the #account-[customer] thread and about 4 or 5 DM groups with different internal people on them for each account. Lots of time bringing everyone up to speed when it could be more unified.

Sure, there are sensitive issues like employee conflict, salary discussions, etc. I'm not saying everything needs to be in the public. But I think DMs as they work in Slack cause more issues than they solve.
