You obviously do not know the definition of free software:
https://gnu.org/philosophy/free-sw.html
Four freedoms must be given to the user for the software to be called "free".
Freedom 1 is:
The freedom to study how the program works, and change it so it does your
computing as you wish. Access to the source code is a precondition for this.
Freedom 3 is:
The freedom to distribute copies of your modified versions to others. By
doing this you can give the whole community a chance to benefit from your
changes. Access to the source code is a precondition for this.
As a consequence, if the user cannot "look at the code", it is *not* free
software.
