Maybe you had a bad experience? As far as I know, air creators ecosystem work out their percentages well, as they do analytics and help improve the quality of content, especially as far as I understand the partnership is based on win-win, the more views the youtuber has, the more our total earnings and they are ready to help implement their recommendations. I'm only not sure how they are with the contract, because I know that some companies have hidden exit penalties (everything can change in life and maybe I decide to abandon the channel altogether.
