Honestly, how much data would the typical company need to transition off?
Some photos, docs, code snippets? Most companies do use those features to some extent, but it should be fairly ephemeral. If you're using pinned messages as a WIKI, then you are really using the tool incorrectly.
Channels and memberships? If you made all of my company's channels disappear tomorrow, you'd be doing us a favor. We'd re-create the ones that matter within a few hours, and the other 90% didn't really need to exist anyway.
The only really true "sticky" part of Slack are webhook integrations. Some companies really do setup some degree of workflow automation around those things. But most of the time, it's just bot-spam. The CEO wants everyone to belong to a #wins channel, which gets a spam alert whenever a sales guy qualifies a lead, etc.

In many cases, all of it.
Data retention laws require many companies retain copies of certain types of internal company communications for extended time periods. This is why some companies have policies that discussions about topics such as company finances or government contracts have to be done via more easily archived channels. But if your company doesn't have those policies and you just use Slack for everything, then everything in Slack has to be retained on the off chance that someone discussed an upcoming earnings report in your company Slack.
