Yes, Braintree you are talking about is a subsidiary company owned by paypal accepts Bitcoin, I remember this is a old news from last summer.
And Braintree accepting Bitcoin is not equal to Paypal accepting Bitcoin, they are different companies.
I agree to an extent braintree taking bitcoin is not paypal taking bitcoin but at the same time when their listed agent is PAYPAL it means that paypal is in one way shape or form accepting bitcoin.
And 2 it just happened in January
