Salesforce-owned Slack is facing backlash for blocking other software firms from searching or storing Slack messages — even if Slack customers have allowed it, The Information reported Tuesday.
The issue started when third-party apps suddenly lost access to Slack message data, disrupting integrations that many users rely on.
Soon after the move surfaced, affected companies and users raised concerns online about locked-down data access restricting how they use Slack alongside other tools. 
Slack has not publicly commented or explained why it tightened controls on message data access, leaving many in the ecosystem confused and frustrated.
This development sparks fresh tensions over platform control and interoperability in popular workplace apps.
