The reason Tyndall spoke of a 'cone' and modern experimenters don't is due to the nature of the light source. Lasers emit a 'beam' of light where the edges are near to parallel (collimated) which is why you see a relatively small spot when the laser is directed towards a far wall. Flashlight emissions (due to the nature of the reflector) are uncollimated and spread very quickly as demonstrated by the much larger spot when the flashlight is directed in the same manner as the laser. If you want to see a 'Tydall cone' then use a larger container and a flashlight with a small reflector, such as the tiny MagLights... As far as the misleading info? Unless you are happy with every CS seller touting their version of "New and Improved" laundry detergent you should take their claims and (mostly) unscientific tripe with a grain of salt and search for info from sources with little or no commercial interests.
