At $1 per IP, given that Apple has a /8, that'd be almost $17M. They could probably cut quite a bit of usage if they wanted to. The real problem is that this doesn't make sense: we don't WANT IPv4 to persist. The sooner we all go to IPv6, the better. Ideally, usage will gradually wane until only obsolete items even use IPv4, then a cutoff date will come from major ISPs and such cutting off IPv4 service and we'll finally pass the last hurdle. At least, one might hope so.
