I think DRM works fine for the actual customers, the companies that are distributing video who need to convince the movie producers that they are taking it all very seriously, so they need to check some “our platform uses DRM” box. It all looks very odd from us downstream. But, still, most people don’t break DRM so it must be doing something.

For a long time the industry worked by shipping movies off the theaters, to be run in projection room secured by kids doing after-school jobs. I think they aren’t concerned with perfection.
