The headline is relatively clickbait-y. Its double their revenue because their revenue is basically 0. Their actual expenses are hundreds of millions, of which this 1.7 million is a drop in the bucket. Once their upfront expenses are paid they will (presumably) be making hundreds of millions/billions in revenue, which means this 1.7m is not particularly important.

You can talk about standard complaints of CEOs with private jets, and I'd probably agree with you here, but there isn't anything particularly egregious here.
