3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing and development of 3D printed parts and devices.
This doesn’t appear to be discussing “3D printing and development of 3D printed parts and devices”.
I don’t think there’s anything wrong with content being curated to fit the community that’s literally the entire point of communities. Just because someone says this should be on a different community doesn’t make them an incel. It’s called content curation, it’s the whole point of having multiple communities.
