Looks like a large firm (Glanbia) bought up these three companies: Optimum Nutrition (ON), Isopure, and Think. * **Think** → Facing a class action lawsuit over false labeling. [Source](https://topclassactions.com/lawsuit-settlements/consumer-products/food/think-class-action-claims-protein-bars-falsely-advertised-as-containing-no-artificial-sweeteners/) * **ON** → They changed the formulation for their plant-based protein powder, and it tastes like shit now. Can personally confirm. [Discussion](https://www.reddit.com/r/veganfitness/comments/xbnfbv/new_optimum_nutrition_plant_protein_formulawtf/) * **Isopure** → Also changed its formulation (seems like for the worse). To top it off, Glanbia tried to give their CFO a €750,000 “retention” bonus.
