Now do FOOF.

My dude, I am not the one who brought advertisement into it.

Of course it’s not unusual to have something presented as knowledge that is false. That’s just lying.

The distinction here is that the conclusion is true, but it is based off of inaccurate information. The conclusion that advertisements are trying to steer you towards is false.

And if the screenshot was taken just before the meeting?

Not quite. Tricks are intended to make you believe something that is not true; in OP’s situation, the other people in the meeting believe that OP is sitting in the location that the background picture is taken from. They can’t actually see the background, however; instead they can see the photo of the background. Their assumption is correct, but the fact that they’re looking at a fake background means it COULD be false.
