Notably, the video game industry pioneered the conditional embargo - where you can publish a review freely as long as it's above a certain score. There's pretty much no explanation for this other than "we want to lie to customers", and there's pretty much no definition of journalistic integrity that would permit signing it, but it happens nevertheless.

(Which, interestingly, means some sites that don't issue numeric scores are barred-by-default from those games. I think that's sometimes been used to spot these embargoes?)
