My salary is 100, I have to spend 99 on food monthly, leaving me with 1 money as profit. If I can eat only 98 money, I double my profit. I am not saying that is the case here, but reducing a small percentage of cost could matter if your margin is small. And in the case of those big corps, you can think of them as multiple companies internally, it’s likely they are doing layoff on departments/ divisions that have thin margin or unprofitable (ie. if you are in ads, very few were probably laid off)
