KDE

I think you may be a bit confused.

Firstly KDE is a pure non-profit: a non profit legally and in spirit. This means money is not a motivator, i.e. we do not use money as a carrot for contributors. In fact, there are no carrots in KDE, as there are no sticks. Nobody is given anything in exchange for their work and nobody is punished for not working either.

Contributors do the stuff they want to do and do it because they want to do it. Hence your proposition "do X in exchange of money" does no make sense in the context of KDE.

Money is viewed as just another resource that contributes to the survival of the project.

Secondly, you are coming at it from a consumer vs. provider perspective. In most contexts in our consumerist society, there is a clear divide between those who use the software and the consumers of that software. In a pure grassroots FLOSS community, like KDE, there is no clear border between the two.

If you want something done, you will be invited to join in the collaborative work of creating it. Even if you cannot code, your skill set will probably come in handy elsewhere in the community, freeing up resources or favouring the conditions that may help to create that thing that you want.

But then maybe not. The fact is, unless you are willing to lay down the foundations of what you want, there is a very slim chance it will actually happen.

I do understand where you are coming from: we all have our perspectives warped by the consumerist mindset of modern society. But KDE is not a business, has no business plan (because it is not a business) and does not use money as a business would.

TL;DR: if you want shit done, come and get it started yourself (or join in an existing effort). Donating will not give you the right to order unpaid volunteers around and make them do your bidding.
