Poor analysis.

Fable is not used because it has extra retention requirement that corps can't sign off so it stays disabled for everybody in many cases.

It's also not winning on day to day work against Opus 5, which is simply available as there are no extra retention requirements and no extra paper work to do with legal.

Devs also don't like that Fable refuses to work on half of their prompts.

Then comes better pricing and on-par capabilities from competition.

> It's also not winning on day to day work against Opus 5

In what universe? Hell, Opus 5 seems to be worse than Opus 4.6 at almost everything.
