I don’t think that’s what he’s saying. You have to ask yourself a question: is offering an expensive upfront subscription for an evolving product an endorsement of assessing future value into your purchase. In my view, it isn’t and it’s not what he’s saying.

What he is saying is that to the minority who will find this a good value or who are okay donating to help them implement new features, go ahead and hit that button. Then separately he’s saying “the price will make more sense to more people as features are added” which is true but is not an endorsement of paying the current price for those promised features. At least from what’s in the article and what I’ve seen.

It’s the difference between saying that you should buy Minecraft because it will become an awesome game one day versus saying you should buy Minecraft because it’s either worth it to you now or you’re okay with helping to fund the development of future features you’ll receive. Those are very different.
