John Deere uses it to go after sellers of unauthorized replacement parts for their tractors.
Non-compliance is a felony carrying a 5 year / $500k punishment. Unlike takedown notices, there's no counter-notice opportunity for the receiving party. So if the receiving party believed the notice isn't valid, they'll need to argue that as a criminal defendant in criminal court.

- "provided functionality" -- either functionality is available or it's not. Whether there is a button for it on the UI or not is entirely different. (However, this sort of seems to imply that the HTML specs are legally binding?)
- Your internet connection is only capable of sending and receiving packets, and it isn't wrong at all to describe "sending" as "uploading" and "receiving" as "downloading".
- It says that you aren't allowed to (among other things) "display" any Content for any other purposes -- other purposes than what? "For your information and personal use"?
- It used to be that you could just copy video files from your browser's cache directory, or you could use hard links -- then you wouldn't even have copied them technically. (Not sure if that's still possible on youtube -- but again what if you had a browser that generated PNG files instead or or before "displaying" stuff on the screen?)
"You shall not download"
