Part of the difficulty here is the way the question itself was worded. The answer itself isn't as bad as an overly broad interpretation of the answer. The question and the answer specifically deal with "a piece of plastic installed to prevent a camera from seeing the reflective tape on the goals ", not all tall pieces of plastic or tall robots. My primary concern is if this Q&A is interpreted so broadly as to say blocking views of cameras is illegal.

Keep in mind this is an inspection issue, not a game match issue, so it's not actually illegal to play defense on a robot with a camera regardless of your design...
