DoD couldn't care less about Bezos' mansion or HQ2's impact on the city's economy.
And running a newspaper that continuously annoys a President doesn't really fit the apparently popular idea that Bezos is spending money to get favourable treatment from politicians.
Especially when that politician you're annoying is known to have a somewhat vindictive streak and doesn't quite grok the difference between being entrusted money and power to use on behalf of a country and owning money and spending it in his own interest
