I feel like a sophisticated adversary could do something with it. If I know your habits and design choices from the leak and I couple that with knowing who you hire, who you don't, what your shareholders want, when you're doing crunch time, etc. I'm sure there's something to be done. This all, of course, assumes a rational market and effectual competition.
But if they had a good bad guy, that bad guy could do something like release something 5% better the Friday before your big announcement. Or an example like if they know your next big thing is automatically coordinating office work then you could astroturf a campaign about displaced middle managers while you release your robotics integration at the same time.
If you were a consumer you might expect an open source version of the CLI that gets rid of the 10x+ inefficiency of the official release. But, yeah, this hasn't shaken Anthropic to its core from my understanding
