That answer is pretty contradictory, don't you think?
"Low to no effort [...] that requires to have a concept and know how to code to even get [it] right".
This very contradiction was precisely the reason for my comment. They're putting in effort, as per your own statements, for something that is freely available.
They surely could put in more effort... but why? Do you go to work on a unicycle cause the car is too low effort? And is what he's doing in any way different from copy/pasting the code in Stackoverflow comments?
