Netflix would benefit from the net neutrality repeal. It's basically bound to get repealed, so they don't have to actively lobby for it to be so (and get the negative pr that comes with that) so instead they can get positive pr just from saying "We support net neutrality!" while not doing anything to actually support it like lobby for it to remail.
They can pay so that: people with really slow internet can have netflix at high speeds, and if competition ever starts to sprout, they can quash it by paying for its speed to be stifled.
