So I'm guessing this is somehow related (and I am only speculating here) to that guy who hacked Stern's SPIKE code, put in the endless hours of hard work, and released the incredible modified JP code with the movie soundtrack & actor's voice callouts. Then streams of the modified code gameplay get posted, then get flagged by the YouTube bots. Eventually this gets the attention licence holder..... who say "What are these monetized pinball streams doing using our intellectual property...... and why does this game we licensed to Stern feature assets that were never negotiated as part of the original licencing agreement? What the hell is going on here?"
If this is what happened (again I'm only speculating), then this likely would have created a huge headache for Stern, who wouldn't be too happy about their SPIKE code being hacked in the first place. Hence this new EULA is released to reign in the rulebreakers, offer Stern some legal protections, and thus agreeing to the licencees wishes in order to maintain relationships & obtain future licenses from them.
The 21st century are certainly interesting times for fair use & copyright infringement laws, that's for sure. SCOTUS is going to have to get involved & rule on it at some point.
