From my knowledge, it’s not directly forbidden yet. But it’s likely there will be laws around this topic and Eleven Labs wants to be ahead of it.

Also by having a system now allows Eleven Labs to influence politicians by saying their current system is good and should be the law, preventing the law from being more strict then they would like. (this is why companies like Apple tried to launch their ‘repair program’ before the actual laws were implemented, to steer the direction)
