Right, the issue here is that the "Rust and Java sense" of memory safety is not the actual meaning of the term. People talk as if "memory safety" was a PLT axiom. It's not; it's a software security term of art.
This is just two groups of people talking past each other.
It's not as if Go programmers are unaware of the distinction you're talking about. It's literally the premise of the language; it's the basis for "share by communicating, don't communicate by sharing". Obviously, that didn't work out, and modern Go does a lot of sharing and needs a lot of synchronization. But: everybody understands that.
