their terms also not about game profits. Let's say in case if $300k spent on Ads to get 200k+ installs and as result you made only $200k back as in-apps payments Revenue from game (so your profit is loss of $100k+fees+taxes) then Unity will demand you to pay them $40k+ just to cover installs amount and you almost won't have control to stop new charges because even if you will shutdown a game then some installs continue to happen from various pirate sources or some small app stores.

It looks completely insane terms for lot of mobile games where monetization is huge challenge and difference between profitable game and company bankruptcy measured in cents per user.
