> "Yahoo and Mozilla have enjoyed a productive relationship together since 2014," said Charles Stewart, a spokesman for Verizon’s digital advertising business, Oath. "We are surprised that Mozilla has decided to take another path and we are in discussions with them regarding the terms of our agreement."
That's not an "or". According to the article, Mozilla is very likely still entitled to payment after terminating. The statement from Yahoo in the grandparent comment makes it sound like Verizon didn't quite realise this possibility and are looking to avoid it.
My first thought about this was that Verizon was pushing for some additional tracking requirements with which Mozilla was not comfortable. Google may be a little more flexible in that regards. Or maybe Mozillians just don't like Verizon.
