The download function is the only pro for Netflix (and that’s only aviable for the limited amount of content Netflix has licensed). If I have buffer issues, I can just switch to another website.

There’s also the ethical aspect. I don’t want to support Hollywood in its current state. I won’t give money to a company that accidentally and occasionally produces a good show while deliberately fucking up many big projects on a large scale because they don’t care about making good content anymore, only money.
