very short-sighted and narrow-minded of course but its an easy target. Nothing easier than saying 'the rich and their business jets are polluting, why don't they use airliners where carbon emission is divided by 50-300 passengers". It sells for that fringe right now.
Paparazi newspapers and weather activists have bashed Prince Harry and wife for using biz jets to travel. Easy to convince uneducated people with populist bylines like that.
