If this is an after-death experience then it really wouldn't matter if you couldn't remember copyrighted works. But beyond that I don't think copyright holders would care if you remembered their works because you're no longer able to be a customer. Same with the ads. If the service works like it did in Vanilla Sky then advertising is also pointless. Dead people don't buy things again. They pay for the after death experience and that's it.
But otherwise it's cool and interesting. Maybe I'm reading into it too much. Maybe there was no message and it was just a fun joke. Or maybe it wasn't based on vanilla sky. I don't know, I feel bad offering that criticism but while I was watching it that's what popped in my head.
