This is why SimpleX makes me nervous. They're run by a for-profit company and whether or not they are currently morally on the right side or not is irrelevant. It's why I personally trust Session more. It's a lot more traditional cypherpunk in development ethos. 

While SimpleX definitely has a LOT of really cool features, it has a way to go before I think it'll be useful for most people. It's sluggish if you're in popular groups, the notifications and message catch-up is a massive pain, etc. And like I said, it's kind of hard to trust a for-profit corporation in this case, even if the developer might be on the cypherpunk side of things.
