Might want to think about selling that one to Disney as well and then writing about your great regrets of selling your substack on substack v2 in ten years, that's gotta be amazing content for another ten posts
Few tellers are neutral and objective, many writers get accused of selectively editing things: Philip Greenspun's account of the demise of Ars Digita springs to mind. Or Jerry Kaplan on Go (mobile startup). Or Joel Spolsky on the last decade of StackOverflow.
I don't view his post as useful or insightful, but instead view it as demonstrating a lack of understanding of normal business practices. It's like he didn't anticipate that this could happen, whereas it's always a risk when you sell out. The exact same thing has happened to lots of other small blog/media outlets, like Kara Swisher's Re/code. This isn't an unexpected situation, but he's acting like it is. And that simply demonstrates a lack of maturity.
