If we look at the funded CCS proposals https://ccs.getmonero.org/work-in-progress/, a lot of the recently funded proposals have very few donors, while the amount of money donated is quite big, which means that they are extremely generously funded by a very small group of people (sometimes just 1 person!).
- Do we know who is funding the proposals? (I know we cannot answer this by looking at the blockchain due to the privacy features of XMR, but maybe there are some accepted theories in the community where funds are coming from?).
- What happens if those few people stop their donations?
