What confuses me is their reluctance to attempt to use other third party distributors (itch.io, GOG, etc.) when Steam clearly isn't working in their favor.
Although the author did mention this in the article. I still wonder how much some of these indie games would benefit from partnering with a marketing consultant. Listing a game on steam is basically free marketing for the game. The author mentions only 1% of his sales are from direct sales. I wonder how much having an experienced marketing pro could improve that percentage.
