It's not just that WB wants to "save" him for movies, its that Fox and Disney own at least some of the TV rights:
Go figure.
(T)he TV rights for Batman are caught up in a legal limbo involving Fox, Disney and a trio of mergers. Bruce Wayne can, and often does, appear on TV shows, but Batman in the cape and cowl is almost certainly off-the-table....
Kinney National Service, Inc. purchased DC Comics (then known as National Periodical Publications) in the late 1960s along with Warner Bros., effectively becoming Warner Communications by 1972. This purchase helped secure the rights to the vast library of DC characters save for one. The 1960s Batman TV series starring Adam West was produced by 20th Century Fox, who still holds the rights to the Batman character in live-action on the small screen. In fact, even though Gotham aired on Fox network, Batman could not appear except for the last shot of the show, since Warner Bros. Television produced it. When Disney split up Fox's television assets in their merger, they almost certainly acquired the rights in that deal. That Disney is in the fight now makes it even less likely that Robert Pattinson could suit up on The Penguin.
Even if the Matt Reeves' TV series was an HBO Max exclusive, the TV rights agreement from the 1960s still applies. Some examples of how the Fox deal impacted Batman's TV appearances include Titans, which used an adult Dick Grayson as Robin on the show. Rumors online at the time also suggested producers used Batman in two quick, dark dream sequences without permission. The Arrowverse did this too, name-dropping characters before trying to introduce them. Since Titans' first season finale was scrapped altogether, WB had to debut the episode or end Season 1 on an even worse cliffhanger. While he never appeared in costume again, Bruce Wayne did join the series for Seasons 2 and 3 and even did some fighting.
