HE will not concede - it's jut not in his nature. There is a remote chance that he could be forcibly evicted by those that he must report to, but it would take a sudden and rather dramatic drop in the ~~quality of content~~ (hahaha I can't even say that with a straight face) amount of money they receive from advertising to make that happen. Thus that is unlikely to happen either.
In any case, does it matter? Now that we've all woken up from the spell - the illusion that things could be both "easy" and free while still being controlled by a for-profit company, just like with wikipedia but without the hassle of it needing donations to continue going forward - why would we ever want to go back, regardless?
