There's a huge difference between compelling not lying vs compelling disclosure. We do require disclosure in some cases like in the ingredient example you mention, but even the it's limited to what's necessary: companies don't have to disclose exact recipes and can hide a lot behind the "flavorings" label for example. I'm not sure if forcing disclosure in this case is good, but I do like keeping a high bar on that in general.
