From an enterprise AI practitioner's perspective, the author responds to Nadella's "you pay for AI twice" remark. They agree with the direction but argue the focus shouldn't just be on "whether the model learns from your corrections," but rather on whether enterprises carefully review terms of service and data usage policies before purchasing.

They emphasize that the bigger issue is the total cost: if a company truly wants to "own" its AI stack, it must bear the full costs of infrastructure, talent, maintenance, and security. In contrast, most companies simply want a sufficient, low-cost, low-hassle solution.

They also highlight a frequently overlooked design issue: in multi-tenant systems, different clients' models and data should not cross-contaminate or share hidden benefits. This should be an explicit architectural choice rather than a default behavior.
