When subscribing to StackAid, you indicate that you'd like to support your dependencies. It's hopefully clear that their dependencies have to participate to receive their allocation. We're also upfront that not all OSS projects are interested or currently have a relationship with StackAid. As a result, allocation amongst dependencies will shift depending on the OSS project interested in participating, and that's an important feature that sets it apart from other funding models.
All of that said, we've tried to be clear in the messaging and setting expectations. We're very much open to feedback to improve what we communicate.
