They still can for everyone else, probably everyone you talk to over Signal, so not much of a protection. Pretty much the only way to avoid that is for Signal to give up that control, don't supply Signal directly and let others build Signal from sources and publish in independent from Signal package repositories, i.e. f-droid, OS package managers on Linux, etc. Even if they don't federate, it will at least make their end-to-end encryption sound, not useless like it is now when everyone uses Signal supplied binaries.
