## Why people pay for it

- Unlimited message history
- Group huddles and external channels
- Unlimited app integrations

## Reasons to keep paying

- Years of message history and channel structure
- Integrations, bots and workflows wired into daily work
- Slack Connect channels with partners

## Risks

- **data_portability** (medium): On Free, messages older than 90 days are hidden; export before downgrading.

Data portability: moderate — Workspace owners can export messages (scope depends on plan); channels, apps and workflows must be rebuilt in another chat tool.
