This is outrage clickbait, pure and simple. The comparison of Steam Workshop to "an online form where you can submit finished 3D models" is so dishonest it crosses over into willful deception.

This is the same Polygon (a video game site) that put out an article complaining about how unfairly they were treated when they released a video showing that they don't even understand the basics of video games. The whole site is problematic.
