Fables is an excellent work of fiction by any metric, not just as a comic. Some of the protagonists are among the most memorable characters in any fictional work. I warmly recommend it to anyone.
Well this is awkward, because after hearing it's in the public domain and reading all these recommendations, I'm interested in reading it, but also knowing that the author doesn't like DC, I don't want to give them money.
Also, DC does have rights to past output, the "new" public domain rights are for the general public to create stories in the universe using the unique creative elements that Willingham formerly retained copyright for, as per his contract.
Willingham and DC are still bound by the contract between them. But, the rest of the world is not. That doesn't mean that DC won't still try to strong-arm anyone who wishes to make their own Fables stories, it just means that Willingham has given the copyrights that he retained as per contract to the general public.
Not the pdfs created by DC. But someone probably can republish Fables, maybe or maybe not using the DC version as a source, and you can download that legally.
