Even within the legal context of one country, you may for example be "a resident" by immigration law while "not a resident" by tax law, or vice-versa.
If you give to a single individual on the street, it would typically be considered a gift. If you gave to a collective on the street, then it would typical be considered a donation.
Of course, humans are at their best when not normal. If you want to call giving to an individual a donation, go nuts. Hell, if you want to call it the moon, even better.
But saying "donation" brings up feels for people. That's exactly why you see people in here adamant that they've been "donating" to their fave indie artists! It makes them feel philanthropic.
Those same feels are why Tim Sweeney used the word "donation". It makes you think a 30% cut is being taken from non-profit pediatric hospitals for the poor - Sheriff of Nottingham style. It's hyperbole.
Patreon doesn't say the word "donate" anywhere on their website. The closest they come is saying how to "pledge support" for your favorite creators by subscribing for a month and canceling.
Patreon does not use the word donate, but they do consider contributions to by “donations” even under recommended tax policy if the artist happens to be a non profit, not that we need to consider taxes to be relevant to feels.
