Money alone won't keep a distro alive
I do agree that distros benefit from revenue. I have and will continue to support various distros with contributions of cash (in addition to troubleshooting and bug reports). It seems to me, however, that this isn't the only problem covered in the article so money is not the only solution.
The main problem Void is facing seems not to be a lack of funds but of disaster planning. The question of what happens if one project member gets hit by a bus is common, and it's to avoid situations exactly like this. Other distros have plans in place for what happens if the lead developer (or other key person) isn't available, for whatever reason. This kind of planning comes not from money, but experience.
I wish Void the best of luck in recovering. Diversity of distros is a benefit to Linux as a whole.
