There are things you can and cannot get away with in life, and those boundaries change significantly when you become a public figure. It's purely bad business to support content which any portion of the viewing public might find offensive. He's been doing this long enough; he should have been aware of where these boundaries lay. Honestly surprised he doesn't have a PR manager or a lawyer who he could have consulted first considering how much money he's worth.
Regardless of what he intended to convey through the offending content, this is entirely his own fault and neither YouTube nor Disney are unjust or incorrect in their decision to stop supporting him and his channel.
the people who wrote the hit piece didn't have to contact Disney and Youtube and lie to them about it
they didn't have to take this seriously and could have just left it alone
they could have just told the truth
but now you've got Disney and Youtube dropping someone because some leftist scumforgets decided that Pewdiepie had too much power and so they wrote an entirely slanderous article on him in which they take what is clearly a joke as a sign of political beliefs, then they lie to Disney and Youtube, who both knew going in what Pewdiepie's brand and style of humor was, and call him the next Riddler in order to stop Pewdiepie from screaming about losing subscribers and views possibly because of a Youtube diversity initiative
