Musicians - the stars that sell more songs get much better contracts than newly discovered singers.
Authors - Steven King gets a much better deal from publishers than a new author.
Game publishers - big game publishers get much better deals from console makers than indy developers. Even Epic got much better support from Apple than indy developers. Do you think I could get Sony to make a “Scarface Edition” of the PlayStation?

Software developers - almost every software company makes special deals with large enterprises.
Cloud Providers - I’m assuming Azure and GCP make special deals with large enterprises. I’m not going to say one way or the other about Amazon since I work at AWS (but nowhere near sales).
