It does however make you think about reusability and keeping consistency in code, in the getCharities example there, is something that could be reused elsewhere.
Sorry, but I don't see why reusability is relevant here - when it was suggested to create multiple 'versions' of getCharities with different combinations of parameters to avoid branching. One could even argue that it is the exact opposite of reusability: duplication.
Unless we have wildly different logic for getting by country or tier - in which case it isn't even about branching as they would be two different functions in the first place, what we would most likely have is this:
Why make the reader jump an extra hoop just to get to the actual logic? And even if we were to force reusability on this, what is more reusable: getCharities or getCharitiesByCampaignAndCountry?
I know the example are meant to be simple, sometimes contrived, but this is precisely why I don't see why eliminating else helps in any way with readability.
