If companies are going to do this then they should be legally required to continue printing/selling all of their legacy content. Because sometimes these kinds of sites will have the random obscure content that the publisher literally doesn't sell anymore, but then the company still gets crazy with them.
"You have our content. Take it down."
"Okay, then make that content available direct from you so people can actually legally access it."
A business is not a person. They should not get all the benefits of being a person with none of the negatives, and then also get all the benefits of being a business with none of the negatives.
Idk, I personally don't think it's fair to throw a hissyfit about it when they don't even bother making it available, especially since the monetary damages are negligable. They're not losing customers when they never had them.
Just because they have the right (or more precisely: they gave themselves the right through lobbying), it doesn't mean it's fair.
They're literally gatekeeping culture.
