This isn't really "new news", it's been a known thing for a while [0] Personally became aware of it when looking for camping cookware; Stainless steel or aluminum are very good materials for pots taken on trip, they sturdy but not too heavy, tho have this issue of not being good for anything acidic due to the increased leeching.
