Between this and the debate around the new macbooks/surface-studio, Microsoft is having very good week in terms on gaining some mindshare and good-will from the technorati and the (traditionally) anti-microsoft press. Slack is great. I'm part of many slack communities and until they move I'll stay (although they are all in the free-tier). While the many millions who are already part of the O365 subscription base (and who probably don't even know slack or why they need them) won't have reason to start a community on Slack I think Slack is safe in the short-run with those who don't pay the "MS-tax" or those who are already part of existing slack communities. And while Slack is a great product (as the IRC on steroids that it is) it is easy to replicate and so MS now did.
