Which is probably the point. If I had a million coins, there's no way in hell I would just give them away and neither would you, but it's bad for the supposedly decentralized Bitcoin in general, when one person/entity holds almost 10% of the entire supply and thus has the power to kill it for years.
If I'm doing my math right, miners will mine what Satoshi allegedly holds in 278 days. His share drops from 10% to 9%. His power to "kill" bitcoin will degrade over time.
No, the rate of new Bitcoins degrades exponentially. Even at the maximum limit of 21 million Bitcoins, Satoshi would still hold almost 5% of the entire supply a hundred years from now. Still way too much.
