I like to think most people are able to read marketing material in the context of the roadmap to understand the difference in performance claimed vs. measured - apples and oranges comes to mind
No, most people would like to be richer for less effort and therefore will invest early in a technology and expose themselves to larger upsides were it to take of, and repeat marketing material without incurring responsibility if it's false. I will not hold you responsible for what you just said, for instance, because I assume you're just someone who read the official communication of the company you're invested in, even if it's objectively false to say that people are expected to understand ambiguity in a way closer to the spirit rather than in a way closer to the letter.
Making marketing material truer will lower the amount of people trapped into the vicious cycle of repeating false claims for the sake of propping up a risky investment, and is good for everyone involved long term.
But short-term, making outrageously optimistic statements will create a large amount of proponents which is what probably financed this report in the first place.
The difficulty is in ramping up truth without destroying too much the franchisees who are the ones who put up the actual money but valued their investment in light of a false/exaggerated statement.
