TBH, Faketoshi only won the right to serve foreign defendants over the issue of copyright, and thus (I guess) to include those defendants in the trial. I think those defendants were already included regarding another issue (the "theft" of Faketoshi's btc and his request to roll it back in the blockchain). So not sure if this ruling is a big deal, the defendants already need a lawyer and need to pay, not sure if this raises their costs.
On the bright side, Faketoshi made a witness statement how he is Satoshi, this could make a nice perjury, I hope this will be prosecuted.
