Asides from what the other replies mentioned, various streaming providers have PC streaming platforms that aren't as good as their streaming apps.
I'm currently watching Canadian and world championship curling, and the rights-holder in Canada (TSN) has a website that logs me out between every single game.
Otherwise I watch mostly Plex, and while there is a 10-foot interface (Plex HTPC), for whatever reason it stops my PC from sleeping when content is paused, so I'm forced to use the non-HTPC interface.
