Used here because of the implied greed and speculative use made of the resources, as well as for the idea of an alleged market of competing interest. Empirically (I've done the comparison), desktop browser UIs have been growing in vertical screen occupation since Netscape Navigator 2 quite continuously, including the most recent versions, while reducing the amount of information and control provided by the interface. (That is, tabs introduced a new demand of some legitimacy. – However, another vertically stacked horizontal bar isn't the single imaginable solution to the problem. Previously, there had been sidebars with extracted link lists, we can do it for bookmarks and reading lists… We're even better at scanning vertical lists. There's quite some dogma involved. Arguably, a horizontal tab list shouldn't exceed 5 items.)
