I'm always surprised too. At least the market is sorta working.
In a lot of ways Netflix won. Many people aren't going to bother pirating their content and would rather just pay or at least subscription hop. We're in the greed portion of streaming where everyone wants a bigger and bigger slice. If Netflix did not create original content, I'm not sure they'd still be around.
I'm shocked you assumed this. Most people develop what makes the money. I'm not even sure who's trying to develop anti deepfake tech.
