The point in such patching methods is to avoid legal problems like this. The MI speech project does it the same way for the scripts. And we actually don't touch that much text. Actually only those with variables in it. The main difference is the voice references added.
You sure can't do anything useful with it without having the game files, which is pretty much the point.
I'm not an expert on this, but I never heard of anyone sued due to a patch like this was released. And there certainly are patches which would be of much more legal concern than this one.
