Banning secret numbers is dumb, but it's also the part of the law which is the most completely ineffective. Do you think you can find a copy of DeCSS on the internet? Of course you can.
The actual problem is the fair use problem, because it prevents you from e.g. creating a third party Netflix or Twitter client without the corporation's approval. Which in turn forces you to use their app and puts them in control of recommendations, keeps you within a walled garden instead of exposing you to other voices, etc. It's a mechanism to monopolize the marketplace of ideas.
Of course, Apple et al have turned this against the creators in order to extract their vig, which is a related problem.
