This is the first time Alex has revealed his true colors on YouTube. He should've kept his whiny attitude and lolcow personality to Discord and Reddit, which are usually populated with his white knights who don't care what he does as long as he delivers a shitty update every five weeks.
The thing is, with the Jiyu drama, only people in the Discord really knew what was happening. The Discord only has a few hundred members - not even a dent in Yandere Simulator's fanbase. This Osana video and its comment section (or lack thereof) are being shown to hundreds of thousands of people. YouTube is where he gets most of his support from, and now that a large number of people are finally realizing what a whiny little edgelord he is, the Patreon bucks are probably going to drop.
Looks like his annoying fans DID end up harming the game's development after all!
