Bram started giving 100% after getting hired full time by Google, I believe, which continued on. There is an update on the Vim homepage now about it stopping, though I find the wording a bit confusing... I think they are dissolving the charity but still sending donations to Uganda? I feel a bit dumb for not understanding it but you can read the update on https://www.vim.org/. Unfortunately they don't have target links for dates, it's the [2025-10-28] update.

The OP covers this question at the bottom; donations still go to the same people in Uganda, iiuc.
