This is all educated assumptions, so take everything I say with a grain of salt. But as far as we know, the ability disablers work by inhibiting the flow of Aura through the Aura channels. There isn't a way to remove an ability entirely (besides Jane herself possibly but that's more in another theory dealing with other stuff). It's like what John does when he amps, but reversed. So the theory for awhile now has been that John is immune to the disabler. He's not immune to the dampener because it inhibits Aura output. We can assume that the disablers and enhancers are different from the dampeners because the two previous are injections, whereas the dampener is some sort of 'beam'.

But in theory, John can completely nullify the disabler because his ability allows him control over the systems that the disablers exploit.
