Imperfect Produce's reply: https://help.imperfectproduce.com/hc/en-us/articles/11500456...
The evidence they provide is broad macro-level statistics about how much food is wasted, but not about where the food they're selling comes from.
The parent article claims specifically that they are getting their food from sources that would otherwise be going to food banks.
The fact that this "reply" repeats talking points with country-level statistics instead of directly addressing the question leaves me feeling suspicious of Imperfect Produce.
