Blocking sports streaming is such all out greedshit™.
Look, if I'm watching hypothetically watching a stream without paying the premium, the commercials that have already been paid to the company are still showing, so that ad revenue is still being capitalized.
What they want is for you to pay a premium to watch commercials during sports.
Cable tv started wayyyyyy back when and the catch was: "pay for TV without commercials!"...which was fine and dandy, and it also had Music Videos!
Then when I moved out on my own somehow commercials on cable tv were a thing and at that point I decided that if I am going to have to submit to commercials, then I shall not pay for cable TV.
