Can't speak for others... but I generally pay for a few streaming services at a time. I find a lot of the UX just poor to very bad. I will favor those with shows that I watch. I still torrent the shows themselves as it's easier (for me) to do that then to deal with the various apps on my Shield (they're still there, as my SO seems to use them for random watching).
The networks can still track (to some extent) what shows are popular as torrents, and use that to inform their other advertising efforts. A break out (good) show may show indicators on torrents from word of mouth outside their network, and they can then feature that show in their banner areas.
These aren't likely "profit" directly, but they are and can be factors. Another point is loyalty from those who are able to pay, when they are able to pay. Assuming prohibitive costs are what is mainly keeping people from paying for the content.
