Here is what I found out what's their Like AT&T did to the DC universe

Since the Warner Bros. Discovery merger officially finalized, the news out of the new studio conglomerate has been surprising. They canceled Leslie Grace's Batgirl movie, which was close to being finished. They shunted some 200 classic episodes of Sesame Street into oblivion. Other HBO Max projects, including the much-anticipated The Caped Crusader from legendary Batman animator Bruce Timm, also got the axe. Unsurprisingly, despite a promise to heavily invest in HBO Max, the company started laying off personnel at the streaming service. For (not so) longtime fans of DC projects on streaming, this is all very familiar because it's what AT&T did to the nascent DC Universe. Warner Bros. Discovery is doing something very similar to HBO Max in favor of Discovery+.

And it's get worse,

On one hand it makes sense in the same way the AT&T decision did. HBO Max was their baby and DC Universe was the risky venture that struggled to earn enough in monthly subscriptions to justify their originals' high budgets. Discovery bought WarnerMedia, HBO Max and all, so they want to maintain their team over the one they inherited.

Yet it seems shortsighted, especially since it undoes all the goodwill in the marketplace the service garnered despite their controversial decisions in the COVID-lockdown era. HBO Max is known as a prestige service with artful dramas and comedies, while Discovery+ is mostly populated with reality food shows and pseudo-science pablum about Bigfoots and other cryptids.

Warner Bros. Discovery will definitely survive this period of transition, and their eventual combined streaming service (HBO Discovery+?) could truly integrate the best of both services. However, at least from the outside, these moves boggle the minds of both industry insiders and fans of good TV. HBO Max is being treated like another DC Universe, and that doesn't bode well for HBO Max or anyone watching it.

We need to stop this madness or better yet, Have Discovery use their power for good of the Warner Bros Media and Cartoon Network, including Hbo Max
