People need to stop with their anti-whatsapp shit. They're awful, I agree. Everyone should be using Matrix or Signal, but people start recommending things like IRC and email, which not only do they mirror many of the same problems, they're unencrypted. Meaning that the content of your messages can be read and viewed by the providers that each party has chosen. Stop using WhatsApp, but don't use this to take your moral high ground and then on top of it recommend people worse things.
