In today’s Cloud Wars Minute, I dive into Slack’s bold move to restrict API access to bulk data exports, effectively blocking the use of its platform data for LLM training and signaling a strategic pivot toward proprietary AI control and heightened data security
Highlights
00:03 — Salesforce has changed the API Terms of Service for Slack, which will stop companies from using LLMs to ingest data from the platform. Ultimately, the new policy prohibits the bulk export of Slack data via the API and confirms that data access through Slack APIs cannot be used for LLM training.
00:21 — From now on, companies will have to use Slack’s new real-time search API. In a blog post by the Slack developer team, the company states that this new API eliminates the need for large data exports from Slack, keeping customer data secure while maintaining support for key use cases like permission-based search.

00:56 — Now, while Salesforce and Slack say the focus is on security, there is another angle being discussed, that this move encourages a shift towards proprietary technologies. It’s difficult to pinpoint this trend. On one hand, we see a push for interoperability across the industry, while on the other, Slack’s announcement on the real-time research API coincided with support for the Model Context Protocol.
01:25 — Data is still the currency that drives AI and sharing it recklessly with any LLM that requires access can be counterproductive from a business standpoint. Companies like Salesforce don’t want to be liable for data used by third-party applications, and none of the major tech companies want to stifle innovation with overly restrictive policies.
