Trademark is a whole separate issue; product classes are not trademarks. (Except in the cases of "protected cultivars" of things like fruit and wine.)
But to try to use your example to make my own opinion here clear: yes, I would be happy with to receive a "knock-off" laptop with an Apple logo on it... provided it looked and functioned identically to an Apple laptop, including Apple's willingness to take it in for warranty repairs. (Tangent: such things exist! They're called "ghost shift" products, produced by the same factory-workers that produce the real ones, when nobody's looking.)
And that's what we're talking about here: chemical analogues that have the same effect on the body.
Note that this is all contingent on the idea that maltodextrin is a chemical analogue to aloe vera extract. If it isn't, then my argument here is moot.
