In the long term they will lead you to something like Finnish food market ( which is kinda duopoly ). Long supply chains without any reasonable way to check origins of ingredients. Multinationals have also much more resources and incentives to hide and mask health and environmental effects of the food.

But worst thing is that to maximize profits taste is "optimized". And optimization doesn't mean good taste but rather "doesn't taste anything so that it won't annoy you even if you eat same thing every day".
