Where did he say that? Closest I can see is this post:

It was near 60F on sunday and the gopp looked less viscous but still thick.
Which makes no mention of the foil seal. Some oils don't even use a seal (PennzoIl) so if it wasn't there at all he might simply not have noticed....
From reading his posts he seems like a seasoned car guy who's always done his own maintanence. Even the uptmost novice could tell if something was "off" when opening and pouring in brand new motor oil.
So if you opened a "sealed" bottle of Pennzoil 0w-20, you could tell the difference between it (keep in mind, you aren't looking for anything unusual, you've done this a million times) and say some straight ND 20 weight? What about a lightweight hydraulic oil similar in viscosity and colour?
The foil seal is the difference with the Mobil product, so I'm curious to see if he recalls removing it on this particular oil change, a question which, despite your posit to the contrary, has not been directly answered.
Please don't mistake my pedanticism here for rudeness. This is a bizarre situation and so having a full and accurate account of every detail is extremely important. There's a lot hinging on the product in the jug matching or not matching what is on the jug and that in turn will determine culpability and potential recourse.
