Just checked the Australian apple store and the luggage tag and some bag charms are still available for sale for pick up. They definitely haven’t pulled it and it’s probably just stock shortages.
Probably an isolated incident that is somehow “news” now.
What I'm guessing happened is that someone reached out to 9to5Mac with the anecdote about the pin falling out of his key ring, 9to5Mac checked the website and saw that all the keychains and luggage tags are "currently unavailable" for online order (which they have been for almost 2 weeks in the US), and jumped to the conclusion that Apple had pulled them because of "quality control" issues.
