> What if they choose to use it for their own purposes or disclose it to some third party? I appreciate the sentiment, but Slack has a privacy policy and a known system for how they make money (they charge customers). Companies don’t just, on a whim, decide to start giving away data, especially when they know that it’s valuable and they have a business model of trust. Slack has this. So does basically every other corporate geared SaaS. Being worried about data security is a real problem. That’s understandable. But companies don’t just “decide” how to use data on a whim — it’s a business after all. When you pay for a product, that direct monetary exchange is the one that firmly identifies who the product is — and it’s not you.
