What happened to my Pixel 6 case

The Pixel 6 case series was a departure from the 'cloth' style of the previous models.  Those really stuck out, to be presented with the option of what looked like a TPU case.  Sure, it still was recycled plastics, so you felt better about it, but it just looked... 'plain'.

But it's a case, so I like that.

Fast forward almost a full year and where the other cases I've had never seemed to budge or anything, the case for the 6 has this weird bulge out around the buttons, like the rubber stretched, where other places had a rigid piece of plastic, it didn't and this is where all the slack went.

Oh well.
