Why hate on the GM Scrolls?

I thought the GM scrolls were the ones that look like 10% scrolls and work 100% of the time that aren't supposed to be available to anybody but GMs (hence the name). If they're intended to be released, wouldn't that be enough reason to not call them GM scrolls?

Anything that gives an effect of something other than a 100% scroll that has a 100% rate of working is a GM Scroll.
