I don't see how the copy issue is worse. It relies on an explicit user action: selecting text in a browser window, and then copy/pasting that into a terminal. This requires three intentional steps. Pages stealing your current middle-mouse-paste selection, however, only requires selecting text in another place, and it seems like the only way to defend against this is by not selecting text. Which, at least for me, is not really feasible.
