...and it's a $1.99 risk ffs.
Tangential point: It's super easy to go off the rails and on a rant, while the real reason behind someone's "bait/switch" is external, trivial, and benign. We tend to judge others by their actions, but ourselves by our intentions. I used a German company's excellent sleep supplement (and later worked for that company, too) which was being bashed on Facebook as "non FDA approved snake oil". Meanwhile, the FDA refused (and still refuses) to even look at anything outside actual drugs, even if you wanted them to. Sometimes your hands are just tied.
