I think feudalism is a misnomer here. Feudalism is a historiographically messy concept to begin with and many Medievalists reject the term outright. But even if we were to distill it down to some simplistic yet workable definition I still don't think whatever we come up with would be applicable to the present situation without seriously torturing the analogy. 'Rentier capitalism' would be more apt.

We already have a term for this. Digital Sharecropping.

I've been throwing around the term "neo-feudalism" and people seem to get the gist of what I mean intuitively (paying dues to the monopolistic ownership class, only now you're working digital land) but your suggestion of "rentier capitalism" does ultimately fit much better.
