Eddy, DMCA only covers if an anti-copying mechanisms such as encryption was implemented. After the government gave us access to encryption and decryption under the Right to Bear Arms, the media industries realized that they couldn't use the encryption to protect their IP unless they had a law to make decryption illegal. The fact here is that the type of CD-requirement used for BZ1 and BZ2 is not an encryption, it is a binary switch in the EXE. Such a thing is not covered by the DMCA.
I know this **** pretty damn well, I am a programmer after all, I've had multiple classes on it.
Selectively picking case law is generally in poor taste. When it comes to copyright and digital media, you can find a case in your favor no matter what your view is. The fact is early cases were quite backward but this case law was later reverse with new case law or new laws.

At the most basic level, yes, however, what type of patch sometimes comes into play. Look at the Rock Patch for Red Alert 2. It is a community made patch that does code edits, quite rude ones considering how it was made. Also, sometimes developers make mods. Look at the entire Source Engine lineup. In the end Community Patch vs Mod is based on the content inside. Official Patch vs Patch in general vs Mod comes into play if the developer makes it.
The fact is this entire debate is probably based on some agenda rather than actual facts. Even if Ken was to come in here and say once and for all if its legal or not, let alone the mod/patch thing, he wouldn't be believed, and he has worked in the industry.

And the thing about patches and legality is based on patches that the publisher must provide support for, not patches in general. Legally, I could make a patch for BZ, granted it wouldn't be much of a patch, and if I added too much extra content it becomes a mod.
