It's a problem inherent in the investor-driven, remote-shareholder corporate form.
Most small businesses are pretty well behaved, because the personal morality of the entrepreneurs creates their business ethos, and in any case they are generally close to their local or online communities, which complain or desert them if they behave badly.
But the whole purpose of investors is to extract profit - they're not otherwise involved, so large corporates have no internal, natural brake on abuse, or incentive to good - and if they achieve enough monopoly there's no natural external brake either - except the government, which in the US is cuckoo.
