Extending your logic. Isn't almost any game available on ESPN+? There is a difference between the games offered on ESPN+ and their standard channels. ESPN is trying to push people towards streaming, but still reserves (for the most part) the best games and broadcast games for the established channels. So saying it is available anywhere there is internet is like saying their is air available anywhere. Your response was pedantic. When the Final 4 is only available on ESPN+, then your argument will carry weight.
I'm not certain what you're trying to argue. ESPN+ is available everywhere with Internet.
