it's strange you try to inhibit a job that is done by hobby and for free,
as you well said, these other tools are commercially based and most cost either directly or indirectly.
the work he did is something exemplary, which guaranteed him techniques and knowledge and leaves a tool that even without commercial use could be the basis for so many jobs.
there is talk of reinventing the wheel, but the wheel is constantly evolving or being adapted for the most varied uses
does not discourage the effort of others, only shows a better path
