Hope they keep going strong.
Just to emphasize this for anyone else who is reading this: Please do not feel obligated to donate.
Yes, it is greatly appreciated, since it keeps the lights on a little while longer and allows us to provide builds and host continued development. However, we regard donations as having no strings attached, and the same applies for using the builds that we provide.
We will be fine, at the very least for a while. Please think of yourself first.
Anyway ... I'd totally encourage everybody to donate to opensource projects and/or its maintainers. Whatever the effect may be, but I think that's just simply appropriate.
However, if donating means that you have to consider your current paycheck size, then it might be more appropriate to put that idea on the back-burner for a while.
If you don't have to make that consideration and/or you feel strongly obligated to donate, then by all means, please do so.
