There are suggestions of starting with lots of other non-open source platforms here, but no mention of Signal. That's downright odd. WhatsApp is a fork of Signal. Why on earth wouldn't you just use Signal as your base? After all Signal open sources everything. That aside, it's a bit of a mystery why anyone would choose a proprietary app whose owner could be in cahoots with anybody and you would never know over an open source app, given the entire point of the exercise to ensure your communications private. Facebook is even talking about monetising WhatsApp chats, and governments are talking about forcing Facebook to store the chats so they can be retrieved with a suitable warrant. Yet people still choose use these apps for private communications. Such is the power of the marketing dollar, I guess.
