How does CA expect to enforce the age verification for Linux?

I get that the bill states a fine will be issued per effected child but who would they fine with Linux?

Since Linux is open source and owned by the community there isn't one singular person they can fine. Maybe they'll try and go after Linus but he only technically owns the name Linux.

Would they go after every single person that contributed to the kernel instead? Or is the plan for them to go after the more "semi closed" distros instead since there's a company to hold accountable?

I really don't see this working out the way CA plans for it to and I'm glad it hopefully won't.
