That's true, privacy is an issue in any centralized service. I don't remember whether it has been discussed on this topic or not, but I'm pretty sure some members seem to think that privacy is not a crucial issue for them. Maybe that's why some people happily suggest or claim that an exchange or closed-source wallet is a good option to store your crypto for the long term. I remember discussing it with other members but they don't seem convinced that privacy is a key factor in selecting which apps/services they use in the future.
