I am trying to convince my group to switch from WhatsApp to Signal and we plan to vote on it soon. So, I plan to use the replies in this thread to compile a list of reasons to use as talking points. Preferably, I need something that can be understood on a personal level as some of my friends are deeply cynical and have no concern about escaping techno-feudalism and surveillance.
It’s simply trust in the organization that maintains the app.
Unless you’re coordination/organizing about legal grey or red areas then it’s not much danger. Meta says it’s E2E but do they really not have access to your data? I don’t believe them. Any data they have would be happily handed over to the authorities just like your protonmail.
Signal just straight up doesn’t have access since it’s all stored at the endpoint and they provide no remote backup.
