While I don't want to even pretend to tell you how to make your decisions, you actually provide your own argument for why non-commercial licenses fail: Just like you can cordon off AGPL code and not let it touch your main project, big corporations are more than happy to juggle accounting tricks to make a certain piece of a project look "non-commercial," if it'll make them money.
In my opinion, it'd be better to force them (by the terms of the license) to contribute changes back upstream, so that if you disapprove of their use, you have the ability to publicly shame them as it happens.
That design looks more difficult to work with than the half-gallon and quart containers that we get in most of the United States (those are waxy cardboard rectangles with square bases and peaked tops), but a lot of people have used them for molds to make block-y things, whether literal blocks, candles, or something else. The waxy coating on the inside made everything easy to remove.
Those, though? As long as there's no smell left, I might suggest just using them for storage. They look well-made for anything from oil to beans, since they're not going to let air or light in.
