Not so fast. "Agency model", which is what the publishers want to mandate, is "retailers have to sell at MSRP". There may be nothing stopping them from refusing to sell through Amazon unless Amazon agrees to MSRP.
That said, lots of industries do work on "retailers pick the pricing", which is the deal that Amazon likes. (Either way, the publishers get to decide how much they charge distributors.)
The "predation" here is that Amazon is willing to take a smaller cut than Apple. That's not predatory. If anything, that's a competitive response to Apple's favored status on a dominant hardware platform.
I would love to learn from a knowledgeable lawyer why the practice of giving software away for free -- even when it potentially harms new entrants by eliminating entirely their potential for revenue generation -- is legal.

I suppose you could argue the services aren't really free, it's just that advertisers pay for them and not the users directly. So Google isn't really providing a service below marginal cost as long as the marginal revenue of advertising is enough to cover it.
Similar considerations happen in a proprietary context. For instance this website is funded and built by programmers whose time is incredibly valuable, yet it is available for free. My belief is that pg sees this discussion forum as an advertising cost for ycombinator. Why shouldn't it be legal for pg to spend his advertising budget giving away a discussion forum when there are competitors that are trying to do similar things as a paid product?
Giving things away for below marginal cost can also run afoul of WTO anti-dumping laws. I am also curious why there are never any dumping complaints made against software companies whereas they are quite common in adjacent markets like RAM chips.
Just bandwidth cost. Literally a fraction of a cent.
There are a lot of costs to software distribution, but the vast majority are sunk costs, not marginal. By contrast manufacturing has significant marginal costs.
This economic fact may be relevant to any decent analysis.
