It is intentionally misleading when the frame-of-reference is not explicitly cited! "Oh, what a tangle wen we weaved...."
If it's intentionally misleading, who has it misled? I have some bridges in my trench coat I'd love to sell them!
Guiness an entertainment company, not a scientific organization. To Lucid it's an advertisement. Neither of these things should ever be taken without a grain of salt. If someone is making purchasing decisions based on the headline of an advertisement in an entertainment magazine, well, I think it's fair to say that's on them.
I just think you're taking this far more seriously than is reasonable.
