They wouldn't need the development costs they now have, they could reduce server costs for anyone who's willing to share bandwidth, they could still limit it to "local/paying users" (with an account / ip addr)
They would immediately push all their content into one place and make it so much easier to use. This would drive adoption of peertube to the next level.
