I noticed this as well. A few days ago I was linked a game engine here when I similarly asked for proof and when I went to the repo and started reading it, the best way to describe it was keyword jargon soup and it seems to be the same for a lot of projects in this thread.

I think it's because it makes them seem...smarter? More technical? But they can't describe who it's for or what the actual design is without consulting an AI.
