The author canceled their ChatGPT Plus subscription not due to cost but due to OpenAI's degradation of the product's performance.
Despite being a devoted user who restructured their professional life around ChatGPT, the author felt let down by OpenAI's prioritization of growth metrics over user experience.
Stanford and UC Berkeley research showed empirical evidence of ChatGPT's systematic degradation while GPT-3.5 saw improvement, suggesting conscious design choices prioritizing speed and cost over capability.
OpenAI possesses superior technology like GPT-4.1 but restricts it to API while limiting ChatGPT Plus subscribers, leading to dissatisfaction among users and a shift towards other AI providers.
