I strongly disagree that there is no evidence that Lockdown mode is effective; there have been numerous exposed, active iOS exploitation campaigns of which none have worked against Lockdown mode. When we're trying to prove a negative, that's actually some of the strongest evidence we can get.

The economics of the device exploitation industry are completely orthogonal from bug bounty payouts; the markets only overlap at the _extreme_ fringes. Trying to use one as a proxy for the other is meaningless.
