It sounds like you're not interested in joining their group. that's fine, but I'm not sure why you're interrogating the OP here/criticizing their group, move on. It's not a good look for the forums.
I am asking legitimate questions to try to peer past the marketing and get a sense of what this group is about to see if I - as a GM - want to collaborate with them AND to see if I can learn anything from them.
Why are you here? Did you just roll up and decide "I am going to involve myself even though I have nothing to contribute and no understanding of what's going on?"
Look, you are welcome to not interact with me. I think we would both profit from that.
