The link shows is a community fundraiser for COBRA donations to the laid off staff. It shows a bit over $55,000 in donations which came from a list of dozens and dozens of people, 52 right now. Stephen G. Perlman, the CEO is in fact in the list of donors, but it doesn't say how much each person donated. There is no indicator anywhere here that he himself donated almost everything there. Does the OP have another source where he mentions having donated $50k personally?
