[Virgin Galactic's passengers] do appear to be wearing parachutes.
First of all, it should be clear that this infographic is by no means objective; it's designed to put SS2 in the worst possible light, and New Shepard in the best.
That said, an "escape system" in the rocket launch context normally means an automatic rocket-powered system which takes the crew capsule rapidly away from a malfunctioning or exploding booster.
In SS2, where the crew compartment and the rocket motor are integrally combined in one fuselage, there's no way for the crew to get away from the motor. The parachutes might save a crew if the airframe fails on the way down, after the rocket motor has burned out completely, but otherwise, they're not very useful as a safety measure.
Because this isn't an informational infographic. This is an ad. And, as such, it is deliberately skewed to paint the advertised product in the best possible light, while disparaging the competing product(s) as much as possible.
As mentioned in the other answer, Virgin Galactic doesn't have a "Launch Escape System" It does have other safety systems in the event of an emergency , but there's nothing that requires Blue Origin to tell people about their competitor's products. Lying by omission is one of the most common, if not the most common, lies that advertisers use.
