Documenting the protocols would do little. You could have a completely documented protocol, as long as it requires some form of secret access key they won’t tell you there would be little you could do with it.

That just takes a crowd, and time

  Sure the DVD and HDMi encryption keys are now public, but I doubt a long-enough encryption key will necessarily be cracked.

    Any key that is in large amounts of consumer devices will be cracked.

      Maybe, but it will also get revoked by the provider and not be very useful any more There are lots of compromised Widevine Level 1 keys out there, but Widevine license servers no longer accept them.

        If the key is in hardware is isn’t quite that easy to revoke, and if it is in software it isn’t quite that difficult to crack.

        All Widevine Level 1 keys are in hardware. It's one of the definitions of a Level 1 key.

Does AirPlay require mandatory DRM? If not, I don't see why the base protocol couldn't be open, with DRM as a proprietary extension.

  There are several AirPlay's. Some do, some have optional DRM, some just rely on device keys (some of which were reverse engineered years ago). AirPlay is not a very useful term at this point tbh, but the Apple documentation on the differences is also garbage.
