Don't worry, Amazon screws authors directly too when they self-publish, by using the cudgel of Kindle Unlimited to choke possible competition in ebook sales.
There's entire genres like litrpg, progression fantasy and cozy fantasy that likely would either not exist or be a fraction of their current size without it.
And authors can make a living, there's plenty in those genres (not to mention romance) who via a combination of patreon + KU + Audible are doing just fine.
I too wish there was someone who could compete with amazon, but the thing is nobody seems to actually even try? I feel like the entire book industry would be quite happy if things had remained stuck in time circa 1990, on their own they would never have invented something like KU.
Sure doesn't help that unless you go out of your way to buy a third-party device, there's platform lock-in, which was never an issue with physical publishing.
It does rather feel like the shoe is on the other foot now. Go back a few decades and publishers were the ones rinsing bookshops for all they were worth. Two wrongs don't make a right of course...
There's nuance to this. A company can achieve power by giving customers a better experience and in that way insert itself between customer and the industry. Thus wielding power in the interest of the customer. A company can also achieve power by giving producers a better experience and insert themselves between producer and industry.
I think my point is that in the majority of cases companies will do both. i.e. (when run "effectively") they will use all available levers.
If they fail to, it will usually be an oversight than a deliberate strategy.
Of course - some companies push harder, overstep more bounds and neglect the possible negative 2nd order effects more. But assuming there's an obvious lever that says "make more money legally" - the vast number of companies will reach for it.
The real lesson is if you let a person or organisation get into a position where they can squeeze, they will squeeze. They won't even be doing it because they are "evil" because the hedonic treadmill makes everyone feel entitled to more. The problem is systemic. We know our failures but don't do anything about it.
