When it didn't happen Roy and another board member resigned in protest. They posted a web site and continued to work for Michael Eisner's demise.
They thought among many bad decisions for WDW and DL that Michael was buying way to many other companies more than the Disney Co. could Keep afloat.
The Final thing was that Eisner had gotten himself a gigantic salary that was bankrupting the company. While Eisner ignored the parks letting repainting repairs go till Disney Veteran thought the polish of magic was suffering too much.
