If they wanted to please buyers and sellers, they would allow eBay users to use the payment method of their choice, including PayPal. Many users, including I, use PayPal, but many prefer different payment methods.
Knowing eBay's history, a rational fear might be that once eBay has everyone using PayPal and only able to use Paypal, they will do what they want PayPal-wise (lax customer relations, holding money, irrational rules, jumping through hoops, etc). Users having the option to drop PayPal is essential to keeping eBay and PayPal from acting poorly because they have a monopoly. If eBay users have had problems with PayPal when PayPal was one of several options, how do you predict they will act when they they know users can only use them? A safe guess would be that PayPal won't be getting better.
