Perhaps I am missing something in this conversation. The conference website clearly states what is funded by a scholarship (round trip travel, accommodation, registration):

The accommodation and registration costs will be published on the Wikimania website. Divide the accommodation cost by the number sharing. A quick look at any online flight booking service or a visit to a local travel agent will get you the cost of cheapest airfares on  the relevant dates (I presume WMF uses the cheaper airfares).

As someone who has attended Wikimania at my own expense, I have had to do those same calculations to see if I can afford it. It’s not that hard to.
