This doesn't fly in light of recent history: first, Signal has some trust issues of its own (I mentioned a couple user-hostile acts in sibling comments), but that aside, do you remember how much praise WhasApp was getting in its early days? There is no guarantee the same can't happen to Signal (though it's pretty clear that it will become a major target for takeover and under significant scrutiny and influence would it ever grow past a certain point).
> Whatever issues Signal Foundation has had, they certainly pale in comparison to Meta's.
At this point I would trust a vibe-coded messenger app over anything produced by Meta. Security and privacy are completely opposed to Meta's business model and track record, regardless of how WhatsApp was once designed, and especially regardless of what their PR army claims. The idea that the same couldn't hypothetically happen to Signal is pure fantasy that's not worth entertaining in this discussion.
