Yes. Hopefully they’ll continue to maintain the mautrix bridges they already have.
Also it’s sad to see Beeper misusing the term open source for the source available SSPL [1]. Beeper is free not to use an open source license. But an open source “license must not restrict anyone from making use of the program in a specific field of endeavor” [2], so it’s misleading to call their demo [3] open source.
I do believe supporting the different messaging services client side could be a better experience than relying on a server to translate between different protocols.
