So, MATLAB invented broadcasting:

"Other people thought that the new operator behavior was not sufficiently
based on linear algebra notation. However, instead of thinking of MATLAB as
a purely linear algebra notation, it is more accurate to think of MATLAB as
being a matrix and array computation notation. And in that sense, MATLAB has
a long history of inventing notation that became widely accepted, including
backslash, colon, and various forms of subscripting."

to be fair, that statement does not say that they invented the notation for automatic broadcasting, just that they've invented notation that has become widely accepted for matrix computation, and based on that their use of the dot-operators for automatic broadcasting is not something they should  have avoided because it falls outside of typical linear algebra rules.
