Dear members,
We just put out this Open Letter to Meta with a call to action to
support true messaging interoperability. Please find the associated blog

Dear Meta Team, Tom Alison, Dick Brouwer, Will Cartcart,
The European Digital Markets Act (DMA) is designed to break down walled
gardens and enforce messaging interoperability. As a designated
gatekeeper, Meta—controlling WhatsApp and Messenger—must comply.
However, its current proposal falls short, risking further entrenchment
of its dominance rather than fostering genuine competition.
The Problem with Meta’s Interoperability Plan //
<https://xmpp.org/announcements/open-letter-meta-dma/#the-problem-with-metas-interoperability-plan>
Meta’s proposed approach relies on restrictive NDAs, proprietary APIs,
and centralized control. This is *not true interoperability*—it is a
closed system that forces third parties to operate within Meta’s terms,
undermining the spirit of the DMA. Key issues include:
*
*Gatekeeper Agreements:* Companies must sign NDAs to access
interoperability details, creating artificial barriers. Managing
these legal aspects increases costs for all parties involved.
*
*API-Based Control:* APIs limit flexibility, can be modified
unilaterally, do not scale for true federation, and have to maintained.
*
*User Tracking Risks:* The approach involves compliance issues of
tracking third-party users at Meta, as well as third-parties
tracking Meta’s users.
*
*Scalability Issues:* Maintaining separate API bridges for each
provider is inefficient and prevents sustainable competition.
The Solution: XMPP Federation //
<https://xmpp.org/announcements/open-letter-meta-dma/#the-solution-xmpp-federation>
Meta does not need to reinvent interoperability. The *eXtensible
Messaging and Presence Protocol (XMPP)* is a *proven, open standard*
that has powered global federated messaging for 25 years. XMPP enables
*direct server-to-server communication*, removing the need for
restrictive agreements and ensuring:
*
*Seamless Federation*: connecting users across providers, just like
email or phone networks.
*
*Decentralized Control*: allowing each service provider to enforce
its own policies.
*
*Enhanced Privacy*: avoiding unnecessary data exposure.
*
*Scalability and Flexibility*: ensuring long-term sustainability.
Meta Has Already Used XMPP—Why Not Now? //
<https://xmpp.org/announcements/open-letter-meta-dma/#meta-has-already-used-xmppwhy-not-now>
*WhatsApp was built on an XMPP-based server*, and Meta has previously
*supported XMPP in Facebook Messenger*. The protocol is already
battle-tested at scale. Furthermore, *Meta is embracing federation for
Threads with ActivityPub*, proving that interoperability works when it
serves Meta’s strategic interests.
If Threads can federate, so can WhatsApp and Messenger.
A Call to Action //
<https://xmpp.org/announcements/open-letter-meta-dma/#a-call-to-action>
We urge Meta to *adopt XMPP for messaging interoperability*. The *XMPP
Standards Foundation (XSF)* is ready to collaborate, continue to evolve
the protocol to meet modern needs, and ensure true compliance with the
DMA. Let’s build an open, competitive messaging ecosystem—one that
benefits both users and service providers.
It’s time for real interoperability. Let’s make it happen.
Kind regards,
Ralph Meijer
