I agree with you. There are so many ways to make this infinitely more efficient. For starters, why are they re-calculating and re-rendering the value every time they get a new donation? Also, they could store those values in a more cold&cached-storage and just make the reads to update from Firestore. Don't use a freaking database that is charging you for every single read and write, to deal with mundane client-side renderings.
