This implies that Space X is overcharging compared to launches from 25 years ago, but is cheaper relative to ULA launches from 10 years ago. But how does, for example, "1998: Deep Space 1 — Delta II rocket — $86 million" compare to "2025: SPHEREx astronomy mission — Falcon 9 rocket — $99 million"? Are they similar payloads? Are the reliability requirements the same? Could there be a reason the Falcon 9 launch costs more instead of less, as we would expect? The article does mention interesting reasons why some cost more than others such as scheduling, hazardous payload, weight, non-combined payloads, etc., but without addressing each launch individually there is no way to address the headline, "Why is NASA paying more?" Incidentally, from the data, I don't see any case of them paying significantly more. It's actually about the same, so even that is misleading.
