Good questions. The airdrop is still ongoing at a decent pace however (cf. http://chainz.cryptoid.info/aur/claims.dws), with a best case reach of 8% of Icelander.

I'm guessing that at the moment the easy airdrop targets have been tapped out ie. tech-aware kids, young adults & their parents/relative, and either the airdrop is successfully reaching a broader audience, or some non-Icelanders have found ways to get some drops.
