I'll borrow yan ruyu's shapeshifting powers and pretend to be a USA NED shill for a moment:
"Oh hoho look at me. I'm secretly part of the USA NED. Every time a new genshin character comes out, we have to say how they will be much stronger than ganyu to show how far ganyu has fallen behind. Eula is stronger than ganyu. Yoimiya is stronger than ganyu. Raiden is stronger than ganyu. And now Shenhe will be as well. Anybody with a different opinion we must criticize and downvote. We need to control public opinion to make everybody view ganyu negatively. And who's goin to stop us. We're NED, the biggest waste of people's money on the planet!"
