her in a pose with tongue out

Yeah, so you can see the logos forming the pattern of the face buttons on the pills.

This is highlighted by the fact she is looking up, with the camera focused on her face.

becausw she's getting high, this is really common "being high" imagery. That's even why it looks slightly sexual: orgasms are just a different kind of high.

but I'm sure as hell not going to tell a woman she's not allowed to be offended by sexualization of another woman to sell Playstations.

Nobody said she can't be, they just pointed out her reasoning doesn't really hold much water, because it doesn't. People can feel however they want about something, none of us can stop them.
