Marketing suffers from that people's attention is a commons. People don't sell their attention, so marketers are free to grab it. And then the inevitable happens: because attention is limited and because it's free, the commons get destroyed. (look up tragedy of the commons!) Destruction has many facets here: ad blindness, hate against marketing, ad blockers, stopping watching TV and movies, and so on.
