This was reported over on [reddit[(https://www.reddit.com/r/starcitizen/comments/15hctp4/correcting_a_wrong_ready_for_anything_kit_now/). The OP doesn’t know why it was gifted. It was on a new account that used a referral code.
The Ready For Anything kit also seems to have been removed from the store. There are still a couple armor kits, but at least they aren’t promoting them to new players.
I’d like to think CIG has learned from this, but it’s probably just damage control.
So wait, who gets it for free?
I don’t think it was really clear. Some new accounts that buy starter ships?
People that did guide sessions got some other set.
