The short version

  • Each has a real cost: Signal signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account; Microsoft Teams resource-heavy application; slow to load and consumes significant CPU/memory compared to alternatives
  • They diverge on capability: Signal covers End-to-end encryption, Microsoft Teams covers Chat & channels.
