There are two lessons we can learn form "information by itself doesn't sell $WIDGET". One is that properly informed people don't actually want that product, and the product should be changed or replaced to meet their actual needs.
The alternative lesson - which is unfortunately very popular - is that if people that are properly informed won't buy the product, then they should be kept ignorant and scammed into buying it.
Or the reality, which is neither of those: people don't become properly informed when you present them with unprompted information. They ignore your pitch and move on with their life. You never reach the state where there are "properly informed" people deciding not to buy your product.
Of course they do. An unprompted pitch is at best an annoyance and at worst some kind of scam. Why would you expect it to be well received after you wasted their time and energy?
> You never reach the state where there are "properly informed" people deciding not to buy your product.
Sure you do. It's why people pay for things like Consumer Reports - so they can get the information they need to decide if they should buy something. This isn't true in all cases, of course, but most people make informed purchasing decisions regularly.
Just note that they may disagree with you, even when you have the same facts. Situations and opinions are highly variable.
If it wasn't clear, that was only one example. Every reviewer, search engine, friend-who-already-bought-one, and so on is a resource available to get information.
This is, however, straying from my point, which was: just because people aren't informed about your particular product doesn't give make it ok to try to trick them into buying your product with manipulative advertising, and throwing your pitch at someone unsolicited is still (at best) rude.
That could easily change if there were no more advertisements and "things like Consumer Reports" were the way to buy things. It would be like a Costco or Amazon Prime membership.
