Meta Announces Discontinuation of Cross-Messaging Between Instagram and Facebook

Instagram and Facebook will no longer have cross-compatible messaging services starting mid-December. New cross-platform chats will be disabled, and existing conversations between the two services will become read-only. The change comes three years after the feature was launched, and it coincides with Meta challenging the European Commission's decision to regulate Messenger as a "core platform service" under the Digital Markets Act. Meta argues that Messenger should be exempted from interoperability requirements because it is a feature of Facebook rather than a standalone messaging platform.
