"It's not at absolute zero, therefore there's some chemical process going on, therefore we don't know if it's causing significant portions of cancer"?
The number of things you can say that about is frankly infinite. You have zero reason to believe that any of the "chemical processes" that happen to an apple (or any food) in long term storage have anything to do with cancer.
This is a great example of correlation not equaling causation. You might as well say that writing years starting with a "2" could cause particular risks that account for a significant portion of cancer because of the different motions of our hand affecting our lymphatic system etc etc.
Irresponsible fearmongering with no foundation whatsoever.
Bad science is building hypothesis and promulgating it publicly alongside zero evidence whatsoever.
The discussion is about stored apples specifically causing increased cancer rates, paired with an arbitrary woo categorization of "living" vs "dead" food. OP wondered why this did not occupy a larger portion of public discourse. Again, this hypothesis exists alongside humans writing more years whose first digit is "2", as evidence-supported cancer progenitors.

Yes, if you walk back the "living vs dead" woo concept and expand the scope to more varieties of foods than just apples and more processing methods than passively storing otherwise intact fruit, then you exit the zero evidence crackpot zone.
Lots of crackpot woo theories are similarly half a step away from real evidence-supported theories. Another example would be biodynamic agriculture, which looks a lot like organic and integrated farming practices right up until you get to the part about burying ground quartz stuffed into the horn of a cow so you can harvest cosmic forces in the soil.
Don't be sorry! Instead of apologizing, all I ask is that you notice, read, and internalize the part where the objection is to "and therefore that's why cancer rates are increasing".
