This doesn't necessarily change the dynamic, though. The government has a finite number of lawyers. Diverting them to write subpoena after subpoena to request Flock data is still a hefty opportunity cost relative to what those lawyers could be working on instead.
Paying that fee would absolutely be worth it in a costly divorce if it prevented someone from paying out.
I'm assuming flock have some sort of legal protection that gets them out of that for regular plebs. Otherwise people would hate them even more knowing they were used for people's personal matters.
