The majority of the corporate world is either already on Office 365 or moving to Office 365 for their email, which could be subject to the same argument.

That said, I think any hacker would die of boredom reading my company's Slack channels before they hit any nugget of interesting information!

CtrlF: illegal, $, credit card info, etc.

Again and again, the issue is not the encryption algos, it's the bits between the keyboard and chair. People are stupid.

Any hacker capable of hacking slack would likely automate searching of interesting information too :) It is not like they are going to sit and read tons of boring chats!

Not everyone is on Google Apps or Office 365. Most of the big corporations outside tech still use self hosted mail servers and use outlook client.

This is changing - rapidly. Even some of the biggest companies in the uber-conservative oil and energy industries are moving to O365 and similar.

There are very few holdouts that have no privileged corporate information in one SaaS or another - SFDC, github for enterprise, Workday, netsuite, etc...

Currently use Google, SFDC, GHE and Workday. NetSuite may be coming soon, we're very much so in the cloud!
