Neat but hackneyed. He's just mad at TNG for snubbing him. I believe Rick Berman's exact words to him when he called was 'What do you want?' It's as warm as lovely as the greeting you'd get from any mafioso member. So I don't blame him for wanting revenge on Berman, GR's lawyer and GR himself for getting rid of him when TNG premiered and in the process trying to be another GR and eclipse his fame which is never gonna happen.
