Slack Terms of Service Review Lowest in Category

"The Salesforce acquisition fundamentally changed Slack's trajectory. What was once a tool focused on team productivity is increasingly an enterprise data platform. The 90-day message limit on free plans is particularly concerning—teams lose access to years of institutional knowledge without warning.

The export limitations are strategically designed to create lock-in. If you can't export your DMs and private channels, you can't truly migrate to a competitor. This is a significant business consideration for any organization using Slack for important communications.

My recommendation: if you're serious about using Slack, budget for at least Pro tier. Regularly export whatever data you can access. Consider whether sensitive conversations should happen on a platform with these data retention and export limitations. For critical business communications, having an alternative is prudent."
