Apple isn't returning all income back to shareholders, so who cares if it's $1B/week now? It most certainly won't be that much a year from now. Why should they care if you paid $700 for the stock, not like they got that money directly.
It's been widely reported that the $15 mil 3rd year salary could cost the Knicks upwards of an $45 million in luxury tax penalties. This is NOT true!
The NBA Collective Bargaining Agreement has a "Stretch Provision", whereby a player's remaining salary and his cap hit may be stretched across twice the number of seasons remaining on the contract, plus one. This means that Lin could be waived before his last year and his salary would be stretched out over 3 years, resulting in minimal luxury tax penalties.
