Disney is bringing Jimmy back, due to its share price falling and loss of revenue, as well as Jimmy's fans being upset with Disney's obvious capitulation.
We are in unprecedented times. Corporations are getting pressure from the administration to bend to their political whim, and then pressure from consumers who vote with their wallets. They just want to make money (the sole reason for a business to exist) and want to take the path of least resistance to the most profit, but are struggling because this administration is injecting itself in ways never before.
Disney cancelled to appease the Trump administration as to avoid any retribution. Losing money was the only acceptable excuse to undo the cancellation (their excuse made me angry and laugh). The administration will forgive them this because, after all, they only speak in capitalistic terms. And it will give them another excuse to blame people on the left by saying they bullied a corporation. It's such a tired song and dance.
