Apple isn’t paying for rights to MLS to be part of AppleTV+. The exclusive deal is for the MLS to have their own “channel” that you subscribe to separately that you can only buy through the AppleTV app.
right, they want to draw people to the appletv app and entice them to subscribe to appletv+, via, for example, a tie-in with "ted lasso". in any case, they'd most certainly roll up those mls subscriptions into total subscriber numbers in any investor relations as "proof" of their strategy.
