Earlier quoted context omitted.
I use Linux and most free software projects allow donations. I even donated to projects I don't actually use, like FreeBSD. I donated money to many free software projects, Ardour, Mozilla, LibreOffice, OpenBSD, etc. This is clearly a false dichotomy.
The problem with open source is, for some reason, the developers feel no sense of obligation to the end users or the people who donate to them. MacOS devs do and will go out of their way to make sure their software is not just usable, but a sheer pleasure to use in every way possible. Yes, there are exceptions (I'm looking at you, Apple, with your Xcode and your Finder) but for the most part that's just the way thing…
An open source project creates no obligation on the part of the developers. Open source licenses explicitly indemnify the authors. Receiving something for free and expecting something more is the essence of the entitled behavior that frustrate and burn out many open source developers.
A donation is a voluntary gift. Like any other gift, a donation to an open source project is understood to have no strings tied to it. Giving a dollar a month to a project doesn't entitle you to round-the-clock support. If you expect something more, have a conversation with the developers to work out a plan.
P.S.: we (https://sheetjs.com/) build and maintain open source projects (our largest is https://github.com/sheetjs/js-xlsx) and we turn down donations precisely because many people expect something in return. Instead, we offer actual paid support plans and additional features.
