It's hard not to think that the idea of dragging the document instead of the viewport makes sense, in special if your trackpad supports two-finger dragging. It also feels very natural to have things like inertia (when the document continues to scroll when you release the pad with your fingers moving and gradually slows down - or halts when you stop it with your finger) in this mode.
Unfortunately, the only way to enable reverse scrolling (and we are not even considering inertia) on Linux is through an xmodmap hack that affects every pointing device. Even more unfortunate, this mode makes absolutely no sense when you are using a clickwheel (such as the one on your mouse) to scroll.
Today many websites are engaged in protests. They protest against abusive and oppressive laws proposed by corporations who are unwilling to adapt to the new reality they found themselves in. Corporations who have corrupted representatives in many countries (albeit the protest is against two laws being considered in the United States, similar laws exist and are being considered all over the world) threaten to enable corrupt governments to quickly and swiftly silence any opposition. For these dinosaurs to survive, our new world of free exchange of ideas must die. We must not allow that to happen.
