I'm all for improving food quality in schools, I just am not sure how best to achieve it. Blaming some corporation is facile. The school board, or someone, chooses who gets the contract. I was friends with the head of our school board for a while, he told me they had to spend a large sum on filling out forms to get monies from the Doed and he was uncertain whether it paid off in the end, it was about 7% of funding.
This is why they had so many "administrators", one reason anyway. This was a "good school system", well funded, they spent over $15 K per student, and it was majority black.
I understand why some folks jump to blaming X or Y for some problem, it's a political driven conclusion, the same is true for other issues like climate change, as I have noted. Reading up on such an issue is "difficult". Forming your own opinions is far harder than just parroting whatever your "leader" tells you is true.
