You're admitting the problem here, anthropic needs revenue to keep growing and growing, yet you're already settled into a willingness to pay of only $20/month as probably a fairly ideal customer, bigger better models just aren't valuable to most people at the price they need to be to make the money back.

Sort of. If they can rely on differentiation and loyalty now, pre-IPO, from their large-but-cheap customer base, they can focus their growth on serving enterprise/other markets, and lean on their existing base as a low-churn-risk (compared to the rest of the AI ecosystem) customer and marketing surplus. Focus is good.
