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.
Plenty of report out there that even if WhatsApp is e2e meta is harvesting as much info as it can from it. Signal has proven to store as minimal as possible.
