The “restrictions” section of Twitter’s developer agreement was updated Thursday with a clause banning “use or access the Licensed Materials to create or attempt to create a substitute or similar service or product to the Twitter Applications.” The addition is the only substantive change to the 5,000-word agreement.
The change confirms what the makers of many popular Twitter clients have suspected in recent days: that third-party Twitter services are no longer permitted under Elon Musk’s leadership.
