While netflix doesn't have a monopoly on tv shows, they do have a monopoly on a given show. If you want to watch Tiger King, you have to have Netflix. However even that monopoly falls down once legalities are ignored. In the 90s the only way to watch US shows in the UK was via the internet, so that's what I did. If netflix introduces adverts, then people will use piratebay or whatever to watch it without adverts.
