Open source is increasingly a kink friendly space where people are encouraged to let their freak flag fly. See also, e.g., cargo-mommy: https://github.com/Gankra/cargo-mommy
I call bs -- that is weasel words. regarding the "truth" that statement, once someone said to me that tech content is like the surface of a balloon being blown up.. each area on the surface gets larger for sure, but also more distant to the others.
kink content is, was, and always will be a "bug light" attractor to certain people.. that is not at all the same as whatever this one-liner says
