This is perhaps too hot a take. I totally understand where you are coming from but I think it is a bit to black and white. For me, you are right and I only use it for really long stuff. For the podcast team, and many who may read this daily malto is probably fine.
A metabolically healthy individual eating within shouting distance of energy balance can certainly consume malto without any danger. If you have no family history of T2, have little body fat like the presenters (and thus probably dont have much fat in your liver either, but its possible. Its more common in some Asian populations to have one without the other) , train some 2 digit number of hours per week (and thus probably have non liver locations to store the glucose) and get the vast majority of your calories from healthy whole foods (so you likely have some metabolic flexibility) it is probably not a big deal if you eat 85 calories per hour in glucose.
I have trash genes, belly fat, only 6-8 hours per week of training and 40 previous years of crappy diet as baggage but I am looking at the numbers from live CGM data that show me I can have pure sugar during any effort above a slow walk and not get an unhealthy insulin spike.
