Pretty sure at one point they said they don't allow the usage of turbo either.
The difference? A turbo controller is a third party kind of thing. The tab-ASD thing is a byproduct of the client.
That's like a glitch to dupe items is on the same lines of hacking to dupe items. It may be an extreme comparison, because hacking and a turbo controller are completely different... but just because you can replicate it via third party doesn't mean it's not an abusable glitch.
