this is a bit weird to say though. PayPal is not a merchant to accept bitcoin but they are a service provider that has been providing payment services and online wallet option to people. now they have added the option to work with bitcoin too.
the way i see it this is another way for them to make more money from commissions while keeping their users and won't affect adoption of bitcoin.
Although I agree with you to some extent, this will affect Bitcoin adoption just by the massive publicity it will get. Just think about the millions of people who use PayPal on daily basis. They simple fact that they will see the Bitcoin logo (probably) and will have the choice to select it as a method of payment is enough. After all cryptocurrencies are not meant to be used in a centralized fashion. But free publicity is always welcomed.
