The memo is ironic, due to Snapchat's infamous disregard for privacy measures. (E.g. SnapHack)

And the Snappening.

That wasn't Snapchat's fault, was it? AFAIK a third party was the one that messed up, or did I eat the Snapchat PR bullshit?

On one hand no, it was definitely a 3rd party that allowed sent snaps to be permanently saved.

On the other hand, perhaps Snapchat is making an unreasonable promise to their users (send data to someone else that will be auto-deleted) that is fundamentally impossible to enforce.

It depends on your point of view.
