Edit: Oh yeah, DON'T USE SIGNAL. Use Matrix instead, offers the benefits of signal without the drawbacks of lack of sync and phone number requirements and is decentralized. The fact that everyone is going gaga for signal as "the BEST messaging app" should be a big red flag in and of itself, because hype trains like this aren't organic, just saying.
I agree of addressing flaws for sure, makes for safer software!
I also prefer decentralized networks over centralize for obvious reasons and your point about signal possibly falling into the WhatsApp route is very valid as well since it has happened to companies before.
At this point it really comes down to personal preference, there are strong arguments for both sides, hard to choose! Hah, will definitely have to look into those protocols to get a clearer picture.
