I was aware of the Yolopark figure, but wasn't sure how official it was since it was exclusive to Botcon. Cool the character exists, she should hang out with a Decepeticon version of Beet Papil!
Yolopark is an official licensee, so it's through them that the figure is officially-licensed.
As of last year, BotCon has basically become like how it was back in the years 1994-2001, where it released figures officially licensed by Hasbro, but the event itself was not actually officially licensed until 2002. But seeing as how BotCon cannot get officially licensed figures from Hasbro directly anymore (since Hasbro has largely bowed out of the convention licensing scene), it is through Yolopark that BotCon can release official figures again.
In other words, Hasbro is okay with Yolopark, and Yolopark is okay with BotCon, so Hasbro is okay with Yolopark BotCon exclusives. It also helps that Agabyss, the current organizers now in charge of BotCon, are a different group of people from those who were members of Fun Pub.
