Hah, Homer Simpson shushed his family because "the commercials are on". They looked at him incredulously, and he said: "well, if we don't watch these, it's like we're stealing TV!"
And it's sort of true, isn't it? The people who have a hard-liner stance on any kind of sharing being "stealing" (I hope they don't borrow any books ever), must surely watch the ads regularly on TV, otherwise how do they justify it?
Me, I'm sorta flexible. I have an evaluation copy of Stuffit Expander which I've been using for years on end, just because I tried to pay, and they'd made it too difficult somehow, I forget exactly how. And I don't feel bad about that. But on the other hand, almost all of the other software I have, I've paid for, gladly. I even paid extra for GraphicConverter once, because for years he did not charge for updates, and I felt it was just too valuable for me. And I've donated to many web sites I found delightful or very useful, or worth supporting.
