“The Court concludes that it is urgent to forbid bad talking machines to deform the public’s artistic sense and unanimously sentences saphir machines to eternal silence“.
Fascinating example of the commercial battle between the Gramophone Company and Pathé in France in the early 20th century!

I would imagine that “J’accuse” in this context is also a light-hearted reference to Emile Zola’s famous exposée of the Capt. Dreyfus case, which in 1910 would have still been very much in the public mind.
Thanks for your comment Anthony! Yes of course, it is a direct reference to Emile Zola’s “J’accuse”.
