Quick run down of the drama
Yandere Dev aka EvaXephon aka Alex Mahan
A typical virgin NEET dweller that came out of 4chan, except he's 👺, he said he made the edgy game Yandere Simulator for "4chaners", too bad NEETs felt sour, they haHAAed him and shat on him, so he went on to Reddit.
On YouTube, controversies started from one YouTube channel called Yandere Datadigger, which exposed Yandere Dev, saying his coding is 💩, and he's taking too much Patreon money for a 💩 game, and the progress is slow.
After that, people jumped on the bandwagon of hate, small YouTube channels started to steal from Yandere Datadigger and upload YandereDev EXPOSED commentary videos, getting 50k+ views easily, I remember some made the same EXPOSED videos multiple times to get more views.
