In a nutshell, from the first link, Einstein was wrong about the particular issue he wrote about. From the second, well, that was sort of a click-baity title (that Hawking himself used). He is not arguing against black holes, but rather is stating that the event horizon described by general relativity is inconsistent with quantum mechanics. Instead, there is an "apparent horizon." You might say that quantum mechanics makes the event horizon "fuzzy." Regardless, there are most definitely black holes.
