If I keep a list of every bookstore in town and what they carry (all publicly disclosable and I honor their requests to stop listing) and people visit it often so much so that I can make a profit by posting ads.
If some wanker expects me to pay him to list his bookstore because I am making money on billboards and he wants a cut, telling him to piss off, delisting him and then watching him go bankrupt is perfectly legal, moral, and just.
If you want to go further you get the whole thing on the creators page, which, surprise, is ad-supported or paywalled. Big content creators basically want the ad revenue (which they get, in large, via portals like Google) and a payment from the portals for the service of getting them that ad-revenue.
Previous such legislation in Spain and Germany was a complete disaster. Spain is now without Google News and ad-revenue is down for many content creators. Germany content producers basically caved and gave Google banket permission to list their stuff.
This is a power move originating from the biggest publishers (which will be the only ones potentially profiting). The smaller outlets are actually against it.
That Google can force a comply or die decision on content producers is exactly the problem.
I don't accept the "they are too big to be required to follow the law like everyone else" argument. I don't accept that Jane's bookstore has to follow the law but Google doesn't.
Why is that OK?
Imagine a used book store did that. Someone comes in with a photo copied book, the store buys and resells it. Or simply inserts their own ads for other books into it.
That store would be shut down and the owner arrested.
Google does it. crickets
