The same author published an article about Lattner leaving Apple on the 10th, and I suspect she asked for a comment at that time. Not getting one from Lattner, she probably asked other contacts she had at Apple and found one that gave her the story about the "culture of secrecy". She then would have reached out to Lattner through whatever means she had, including Twitter (https://twitter.com/Julie188/status/819216603086733312 https://twitter.com/Julie188/status/819216603086733312). I guess maybe "several" was a slight exaggeration, but 2 days is plenty for a story like this.
