There's also the issue that the most recent publisher apparently did not make a good enough counteroffer. That suggests the Fleming oeuvre is not selling as well as it did in the past. Could be an uphill climb to reap a significantly larger profit from "self-publishing" these titles.
I don't think this is revolutionary as such. Numerous classic books have had their rights returned and been ebooks for a while now, usually published by a--wait for it--small press.
In recent years, there have been discussions about whether or not the James Bond franchise bring on a female Bond. There's a strong argument against the idea--Bond is a masculine fantasy. A cool dude with cool gadgets and sexy babes.
Only (to the best of my knowledge, as a non Bond fan), that's not really true anymore in the films. It's my understanding the Craig films are all about how much it sucks to be Bond. He's a lonely alcoholic.
But... did this actually work to bring a new audience to Bond? The old school Bond fans are, well, older. The Fleming estate needs to worry about what happens when the old school fans die off. IMO, the current model of Bond doesn't really appeal to younger people. Unless their parents imbued them with a love of Bond (the way my dad shared Star Wars with me, when I was young), younger people don't have an attachment to any of the old school cool of Bond. (Speaking in generalities).
So, really, to attract a new audience, the estate should do something drastic... like bringing on a female Bond. IMO, it's a genius creative move. A simple swap that changes all the narrative and power dynamics. What a breath of fresh air for the franchise. But maybe it's too far for the old fans / not enough for the new fans.
Explain then why I'm not a small press.
You aren't a small press because you're not distributing books yourself. You are distributing books via Amazon (and possibly other retailers). A small press has deals with their distributers (including Amazon) and manufactures and distributes their own paperbacks.
Now? Does that mean the authors who are raising money for hardbacks on TikToks are small presses? Not exactly but kinda sorta... there isn't a firm line. But, assuming you are allowing Amazon to do the vast majority of customer service and distribution, you are an indie author. If you start taking over that work, acting as a publisher in other capacities (negotiating contracts with bookstores, for example), then you start moving to small press.
There's also the total volume of sales / money. I don't have any idea how many books the Fleming estate moves, but I imagine it's enough that paperbacks are a big logistical issue.
