I think you mean DMA, not DMCA. DMCA mostly protects copyright holders. DMA is about protecting users and competitors from platform lock-in. Bending for Apple would just make that lock-in harder to challenge.
But I agree, that's probably not what OP meant.
Now all it needs is send some letter to github and they take down content, no questions asked, how is that better? It is for court to decide.
It's a lot easier for a large plaintiff - like a record label, a movie studio, or a software publisher - to file a lawsuit than it is for a small defendant like a web site operator to defend against one.
