I am not sure if you're supporting, or opposing what Moolenaar does here. But a large difference is, that, although i am not sure if there's any sort of transparent reports available on the project, they don't ask "donate so I can keep working on vim", they specify "Donate to help poor Ugandan children"
That's what I'm saying, in part. Mr. Moolenaar's reports on his own on-the-grounds activities are quite clear (from what I remember now, a bunch of years later), and the goal of ‘build some schools’ doesn't make me wonder ‘what exactly does that mean’.
Moreover, the encouragement to donate to that charity is written into the license of Vim, and still I never went ‘ugh, why does he pollute the software with politics’ or anything like that.
They absolutely do say "To motivate Bram and others to continue working on Vim please send a donation." It's the second sentence on https://www.vim.org/sponsor/
They GO ON to say that they'll use the money to help kids in Uganda, which is great (both for transparency and the thing itself).
