Slack does not have vendor lock-in [1], which implies significant cost and thus inability for most customers to switch to alternatives. In case you didn't know, Oracle has lock-in over their customers because their platforms expose proprietary features not delivered by competitors, or because they have certifications demanded by law in certain industries. The cost of switching from Slack to something else is insignificant and there's nothing that Slack can do to prevent competitors from emerging, short of burning cash to acquire them like they did with Hipchat. Slack does not even target the market of Oracle, because big enterprises prefer and even require on-site solutions. I've worked with German companies threatening to fire employees if Skype or Slack were found on company owned computers. Comparing Slack with Oracle is like comparing Snapchat with Microsoft Exchange. [1] https://en.wikipedia.org/wiki/Vendor_lock-in https://en.wikipedia.org/wiki/Vendor_lock-in
