People are upset they raised 50 million, how many employees? How long does that keep their lights on? Maybe if they were raking in hundreds of millions I would be inclined to be outraged but if I make a startup tomorrow I cant just donate my VC bucks to every open source project I like until I have some real income coming in or my investors will want my head.

You once again drag things in a wildly hyperbolic direction. Nobody's talking about throwing money around wildly at unrelated projects. When there is a single project that sits at your very heart, without which your entire startup is a nonstarter, yes, donate.
