It isn't a question of sympathy. It's a question of the law and its interpretation. If this song truly warranted being sued for plagiarism, and obviously you feel it does, then I've got a whole crap ton of songs from the 50s, 60s, 70s and 80s when I was really into music that are just ripe for the picking for any lawyer who wants to get rich.
Why don't we start with every 16 bar blues song ever written because hell, they all sound the same from beginning to end. And I'm not talking just 7 notes.
Sorry, but going by what has passed for "original material" before artists started getting shit faced greedy, there is no way this thing should have ever gone to court, let alone actually side with the plaintiff.
