You answered the question in your post. They want Hasan's audience, which means giving empty compliments and hollow promises to Hasan. Hasan is not friends with any of these people, he is a business associate at best and a mark to grift at worst.But for some fucking reason Ludwig bowing down to this imbecile is the thing that I don't understand.
I remember a few years ago I heard he was doing the faggy GTA RP shit that gets popular every few years among content creators and I saw a few clips of every one of the other content creators licking his "characters" (from what I saw it was just him playing an "exaggerated" version of himself) taint spotless. Pretending his midwit political takes and general douchebag behavior was the height of genius and culture. That is all that is happening less obviously with the other influencers who fly around him waiting for the chance to take another bite of his meal.
Its all fake praise, its all to get his audience, its all to get his paypigs to open their wallets for them. There is nothing more to understand.
