Agreed. Not sure why people read the text to say AppleTV+ gets all the games:
From early 2023 through 2032, fans can get every live MLS match by subscribing to a new MLS streaming service, . . . . A broad selection of MLS and Leagues Cup matches, including some of the biggest matchups, will also be available at no additional cost to Apple TV+ subscribers, with a limited number of matches available for free.
I expect the subscription will be annual only, otherwise too many people will drop during the off-season and maybe not pick it back up until May or so. My completely uninformed wild guess is $59.99. It has no real analogue. You're obviously getting less than say ESPN+, except when it comes to your local MLS games, where you get more. The other "all-inclusive" league subscriptions -- NFL, MLB, NBA, NHL, Premier League, exclude something so the league can leverage their IP monopoly and force you to hold multiple subscriptions to get every game.
