One of the most important things a FOSS (and not only) engineer can do is learn to say no. And then decide if they do it for fun, or want money. There may be some overlaps, but it should be crystal clear which is the main one. This is 100% their choice. Trying to sit on two chairs usually ends in misery. And if they treat it as a hobby (fun) and a company, NASA or someone else needs a fix or a feature ASAP, well, they can always do it themselves. You do it if and when it works for you. The software will likely be better that way, too. My 2c.
