TheBlockZone review for Kitenzo ‑ Bundle Builder

I was recommended the app by someone, installed it (admittedly, did not check pricing beforehand) and to my surprise it's 3x more expensive for Shopify Plus users while offering no additional features/benefits. On the principle of "if they can afford plus they can pay us more too". Immediately uninstalled. Correct me if I'm wrong and if there are actual additional features for Shopify Plus users which explain the 3x price increase.
