My understanding was that they leaked the key that the rabbit backend uses to make requests to elevenlabs, and were just too lazy to change it. I could easily be wrong though
I would imagine that the devices aren't making elevenlabs requests directly, but just making requests to the rabbit backend, which forwards the responses. if I'm wrong, then that's quite impressively bad security
It doesn't really matter if you make piracy more difficult if you don't make it impossible. Only one person has to figure out how to rip it, then everyone else can watch it
