Those chains must serve very large number of customers so they must focus on produce that is easy to pick, store and sell. Looks good and survives (even gets ripe during) transit. Taste is often secondary.
You wanna fight that? Fight all regulations for small and local producers, even if it sounds like it’s well intended (hygiene, quality standards, subventions). Talk to your representative about it too. Finally, buy local and from smallest producer you can find.
