The long fight to make Apple’s iMessage compatible with all devices has raged with little to show for it. But Google (de facto leader of the charge) and other mobile operators are now leveraging the European Union’s Digital Market Act (DMA), according to the Financial Times. The law, which goes into effect in 2024, requires that “gatekeepers” not favor their own systems or limit third parties from interoperating within them. Gatekeepers are any company that meets specific financial and usage qualifications, including Google’s parent company Alphabet, Apple, Samsung and others.
It’s still not a standard as long as you’re relying on google for the majority of features.
Like I said in the other comment, those features are all present in the Universal Profile which only lacks e2ee and those weird sticker things.
All the things we would want, file transfers, video, high quality pictures, real group chats etc are all present
