That said, if you really wanted to impress, you'd improve the visibility of your practices for each individual developer, by providing a dashboard that fully discloses revenue-over-time, along with proactive notifications when your terms change. The MVP here would be a single email sent when the 2% term changes.
This business model where the providing party retains the right to change terms arbitrarily has always concerned me, in the same way something like an indentured servitude contract would, and yet they are all too common. But its everywhere, and no self-interested business would take steps to reduce it's power against the counter-party. There is a whole set of problems here that neo-liberal capitalism not only cannot solve, but actually seem to make worse. It's easy to point the finger at a single dev, or a small team, and say "you're unethical!" but in truth I think the statement is more informed by the ability to identify the actor than the action itself, which is endemic. (To take two examples: variable rate mortgages, and credit card debt, neither of which are modeled by consumers and both of which are certainly gamed by the counter-party.)
