In the United states players like Cloudflare have demonstrated twice the can and will de-platform entire communities for controversial speech. senator Joseph Lieberman, with a single phonecall, had wikileaks immediately deplatformed from AWS. All it takes is a violation of a term of service and that service vanishes.
Increasingly Moxie seems to value the developer experience over any project goal for Signal. its still AWS, it still depends greatly on google services and play store for distribution. Begrudgingly hes added a secret-ish link on the signal website to download the APK directly, but he still ardently refuses to publish the package on FDroid.
and as for his "federated services are stuck in time" argument, these are glaring architectural issues that have plagued his application for five years. The only tangible evolution of signal in the past year has been new cat and dog stickers that no one asked for.
