Their business model now is going to be focused through the DNDBeyond portal as a hub where you can keep any rulesbooks and supplements stored under your account. Also subscriptions from DM accounts and more digital content they are releasing down the line. As they are no longer deriving most of their revenue from physically printing new books, doing away with editions makes sense. It’s easier to keep selling new stuff to your customers if they don’t need to throw out everything and start from scratch every few years.
I don't know how much they get from licensing the IP, but given the likely huge success of BG3, whoever is the next licensee will likely pay much more than Larian did, and I assume licensing is a major part of their business model.
