Agree, Love stories dominate in general(music, literature, movies,blogs). Other than promoting stuff from other genres that doesn't change what gets the most views and what the common market likes. No cooperation can change nor wants to if that makes the most coin.
Trust me alot of the time readers don't wish read outside their comfort zone and genre's like horror and heavy world building fantasy are niche.
Everyone is allowed to complain about it but really nothing can change that fact.
