It's only odd if you model economics as a cooperative venture between a society trying to build better collective outcomes, and not as a competitive system. Additional capability and information can never hurt a single actor taken in isolation. But added capability and information given to multiple actors in a competitive game can make them all worse off.

As a simple example, imagine a Prisoner's Dilemma, except neither side knows defecting is an option (so in effect both players are playing a single-move game where "cooperate" is the only option). Landing on cooperate-cooperate in this case is easy (indeed, it's the only possible outcome). But as soon as you reveal the ability to defect to both players, the defect-defect equilibrium becomes available.
