No, they definitely leave out the chicken part.

Because they don't want to spend/waste money maintaining certain features of a product that are less profitable? Or …?

Because they prefer spending money on sales, marketing, and lawsuits than maintaining / improving their products, even their most profitable ones.

Surely if that is true, which I seriously doubt, this is partially on the buyer for not choosing products based on which is the best, and therefore not giving Oracle any incentive to spend on improving their products.
