I asked a forum dev-mod if he could add an option on a new forum (Oculus Rift) a while back if we could at least have an option to open external links (outside of the current forum) in new tabs with a left click. The majority of the research and tech forums (especially) I frequent have this as an option - it just make sense, somebody posts a reference link and you want to look at it without losing your place in the current thread, indeed if it's a picture or diagram having it load up whilst you continue reading is a bonus. I was shot down - apparently I am lazy for not middle clicking or right clicking on such links, citing that such programming practice is deemed unacceptable behavior as people don't like new tabs or windows. Which struck me as strange.
Middle or right clicking on a tablet is a PITA. Especially if a post or thread contains mostly links to external reference content.
Perhaps the pop and popunder is more a human decision than a logical one, and therefore a target for nefarious manipulation. So the extreme unwanted popunder must exist purely for nefarious purposes, shirly ?
