Imagine if this policy had a real-world counterpart. I can picture a conversation going something like this:
"Hey, is there a Lowe's around here?"
"Yes. But legally, I can't tell you how to get there without signing a license agreement with Lowe's."
"Uh... OK. How about a Home Depot?"
"Sure! Turn right on Main Street, go 3 blocks, and it's on the left."
