It's worse in the most important aspect for messaging: it is not end-to-end encrypted by default. It wouldn't be crazy to assume some could get access to your messages.
Besides the obvious downside of not being meaningfully encrypted (even pointing out transport encryption as just "encryption" is borderline deceptive marketing these days, IMO), until recently it also had a very dubious business model.
It now seems to be pivoting towards ad support, but isn't this exactly what people have been trying to get away from Facebook for?
