For those who were asking about the #interoperability models for #messaging apps @matthew discussed at the #DMAWorkshop a while back, here is a paper by interop skeptics that explains them (and mentions the workshop as an inspiration).

I hope someone at the #DMAWorkshop today is going to bring up the issues I wrote about at @osi last August about making app stores #OpenSource friendly
https://blog.opensource.org/how-to-make-app-stores-friendly-to-open-source/ - right now they are talking about FRAND as the solution, which it definitely is not.

Wow so the #Apple lobbyist speaking at the @EU_Commission #DMAWorkshop on #AppStores refuses to answer my question why his company should get to decide what software runs on their devices -- after he spent 15min doing PR blah blah about how #iPhone is the best. 🤦

Thanks for your great work at #neochat #kde and representing them also at EU Commission

I wrote a bit about my experience in Brussels attending a workshop from the European Commission, in case this interest anyone :)

The workshop has wrapped up. Huge in-person and remote audience shows the great interest in interoperability and the DMA.

I was here because @osi paid me to come - I would not have been here otherwise. If you want more, please consider joining!

It's funny to hear a Meta layers speak about opt-in being a requirement for Whatsapp, but not in the context of data collection but instead when allowing other servers to communicate with them. #DMAWorkshop

#DMAWorkshop
Meta lawyer is again reading their prepared statement in a panel on "exploring the technical aspects of interoperability". Basically is is lining up a whole load of reasons to make #interoperability opt-in and to deny requests to interoperate.

Pity they didn't send the people who wrote the statement.

Today the European Commission hosts the "The #DMA and #interoperability between messaging services" on the #DigitalMarketsAct.

Nice to read updates here at #DMAWorkshop from @webmink (OSI), @ilumium (EDRi), @matthew (Matrix),
@carlschwan (KDE),
@raphaelrobert.

Also present: vzbv, @BERECeuropaeu, Mozilla, Cisco, Facebook, PEReN, @BNetzA, Wire, Paul Rösler.

#DMAWorkshop
The Cisco speaker notes that we have been seeking interoperable messaging for over 20 years, but fails to note we have had it a couple of times before and then had it broken by gatekeeper platforms abusing their market power...

#DMAWorkshop
I have to observe that the stakeholders who only sent a lwyer to this messaging interoperability workshop are clearly indicating their intent by doing so. The people who want to make it work sent people to talk about solutions.

#DMAWorkshop
Meta speaker is a lawyer who has just spent his full slot pouring cold water on any approach to messaging #interoperability on every imaginable ground and dismissing all the existing entities running client=side bridges (e.g. iMessage and Matrix).

#DMAWorkshop
Matrix speaker @matthew not only explains the four architectures for messaging #interoperability and then demonstrates one of them bridging WhatsApp and Google Chat via #matrix

Meta speaker next up "is new to all this" and just reads a prpepared statement.

I wonder what the problem is going to be.... ?

#DMAWorkshop
Cisco speaker considers anyone requesting messaging interoperability under DMA art 7 as a "competitor". I wonder if they consider anyone sending an SMS or an e-mail as a competitor as well? Seems this way of thinking is not going to lead to good #interoperability

#DMAWorkshop
I asked what ability the DMA art 7 offers citizens who run their own messaging servers access to interoperability. Most speakers were confused by the idea of "users with servers" but EDRi's @ilumium noted that there is no minimum size of enterprise entitled to interoperability and it will be a matter of enforcement by @EU_Commission to ensure they are not blocked by gatekeeper bureacracy.

#DMAWorkshop
EDRi speaker @ilumium a breath of fresh air explaining the problems blocking messaging interoperability are not a lack of technology or standards but a lack of will by the gatekeeper platforms. Now showing UI mockups of how to do it.

#DMAWorkshop
Speaker voicing telecoms industry view believes technical barriers must be overcome to enable messaging interoperability and advocates open standards - without mentioning the need for any used to be royalty-free.
