This was disabled by default in (classic) Opera (since it was a weird microsoft addition). Was surprised how many sites do this when I switched browsers. At the same time, it's better than those times when you had flash buttons to copy link. So I think it should be allowed to change clipboard on user's action (can it be detected?). But there certainly shouldn't be an event to change clipboard that is fired after the user copies something (selection copy, keyboard shortcut, browser ui, ..).
