I'm not sure where you're getting that from, but in any case Jack and Pete have been around since the beginning. They carry their parent's legacy and vision, and they founded the corporation that SDC evolved into. They don't need to "take" the title from anyone; it fits just fine. I'm sure Founders day will give plenty of homage to Mary and Hugo.
I'm already putting it in my schedule to be there for that weekend. Sounds like it will be a great opportunity for a big SDCFans meetup?
