Maybe so, but if they are scared out of buying with the truth then so be it, is it better they learn after they have lost multiple hives to mismanagement caused by not telling them the whole truth? I think not.
The glossing over serves no purpose except to discourage those who fail when they follow the proposed method and they then feel they must be terrible at beekeeping, terrible at caring for bees and just terrible at the whole business. If they go in with eyes wide open to all the pitfalls they will come out better at the end of it without feeling like a total incompetent. Beekeeping is hard, selling it as anything but is IMO misrepresenting the truth in order to garner sales.
Slick marketing strategies that gloss over the reality tick me off, right from those who sell old varieties of plants with new more attractive names, those peddling fantastical cures for ills to those peddling 'easy' beekeeping methods. Look a person straight in the eye, tell them the honest truth and guess what, most people will accept all the caveats without question.
