Unox is not the Unox of old anymore, they recently dropped a few popular products, and changed recipes of other favorites. And then there is the pricing of some of their products, their rookworst is getting quite expensive but tastes worse.
Conimex I always found expensive and of lesser use than better "asian" brands.
So, in short, it does not surprise me that Unilever now wants to get rid of them, they did not nurture the brands in recent years.
