Yes, NHL blackouts are a great example. You want to watch your home team? Great, you have to subscribe to what they refer to as your “RSN” (regional sports network, usually a regular tv channel).
But the RSN doesn’t show all the games across the league, nor will it show playoff hockey. So you need to also subscribe to a big streaming service like Sportsnet.
It gets worse: your RSN may not offer a streaming service. So you need an old-fashioned cable package to get it. The cost becomes ridiculous, just to watch hockey.
