OK you should also get a part of that. Donations are very non commital for both sides. You aren't expected to do what your donors tell you to. It will help you spend more time on your projects. Like it's in the interest of the users to give you money.
It’s not in their interest to give me money, they have no interest in that at all. They simply want me to continue working and updating my project so they can keep making money.
I don’t need a part of their money. Those weren’t the terms that I put out my software with. Imagine if you had to donate money for every package and library you used. Building applications would get very expensive quickly, when it could just as easily be cheap and free.
