I mean its very clearly a PR stunt to make Blue Origin and Bezos's space efforts more of a name brand like spacex. Making it a name brand likely has some benefits to Blue Origin's bottom line.

Okay, so its just normal marketing like what every company does? I guess maybe the word 'stunt' threw me off.

That's a good point, the point where common marketing/PR transitions to a "stunt" or "is over the top" is really subjective. A lot of people put space flight on a pedestal and so have a low bar for such a stunt.
