Not sure how Marmite figures from the ethical POV, but the new Marmite peanut butter tastes to me just like very mature cheddar when spread on toast (and possibly when not spread on toast, but that's how I tried it). It almost sated my yearning for proper cheese on toast – something no vegan cheese has ever done. I didn't get much of a peanut or Marmite flavor from it, weirdly.
