I can understand your frustration to some extent, but I won't apologize for sharing information that I believe is valuable to our readers. Apple sending out a new memo a few days later is beyond my control. I think something along the lines of "don't shoot the messenger" applies here.
Edit:
Affected users will still be able to get their battery serviced in 15 business days though. That's not much longer than it is taking customers to be sent entirely new MacBook Pro models due to the part constraint. It's simply unfortunate that people aren't getting an essentially free MacBook Pro anymore, but that was merely a bonus, and Apple will still be helping customers that truly need their battery replaced for the exact same cost.
In fact, this puts an end to people who are buying eligible models off eBay or Craigslist just to take advantage of the chance to essentially trade up for cheap, and ensures that users who truly need battery service will receive that repair earlier than September 15, 2017, the original date that Apple quoted the part constraint ending on. Nevertheless, if you want to blame me, I understand.
I stand by my commitment to sharing valuable information with Apple readers, as is my job as a MacRumors contributor. I don't control Apple's subsequent actions.
