What are the differences between Taza and any of the other messaging platforms?

If anything it is less secure because your traffic isn't mixed in with everyone else's.

If you are using Taza and I'm a government, then all I have to do to get real time tracking, that can include locational data, is get phone companies to send me all the metadata on phones that emit this type of message/packet.

This is making tracking easier, not harder.
