It goes both ways, YouTube willingly starts business agreements with these people and makes money off their content.

You can't act shocked and surprised if a mentally ill person snaps when you've been happily profit sharing that mentally ill persons content and then change the deal.

YouTube/Google likes to think these relationships are all one way and not think about the consequences of their choices and algorithms on peoples lives. I'm actually surprised it took this long for this to happen, it was a morbid inevitability in my eyes.

If YouTube/Google can't understand when money is involved actions have consequences then maybe the whole partner program should be scrapped.
