It seems like Anthropic is constantly changing the rules and pulling out rugs, and always entirely by surprise. I’m not sure if they’re incompetent or just careless, but I stopped paying them because of this a while ago, and my days are much more interesting and enjoyable using my own brain instead.
As long as they keep losing money and are reliant on investments to pay their operating expenses, they are going to be thrashing about in search of a sustainable business model and I don't blame them.
