Not to defend oracle, but if you use software legally - subject to open source or whatever licenses - then the question of whether or not you are a leech isn't relevant to anything. You'd not base any decision on it; it just doesn't matter. Someone is providing something for free, and you're using it. As intended. re: charitable giving. If they're giving, they're giving. Doesn't matter what the motive is. "huh, they're only funding a cure for cancer/starving kids/etc because it looks good". So fucking what? What are you doing to help those charities? Typing is easy, huh!
