It could be an A/B test to see whether people without an existing subscription care about Claude Code (CC) at all. If they sign up then CC is disabled (or not as it is not really an issue to offer more). Capturing that info would definitely be useful to a growth team.
They need to give the non-code service a different name.
And a slightly lower price.
If it succeeds they can adjust pricing later.
Otherwise they are messing with their new and old customers heads, regarding a service with a name that ought to be reliably interpretable. And seriously messing with their own credibility. Wrong kind of A/B test.
This is incompetence which i would normally discount. But Anthropic seems to be falling all over themselves to irritate customers.
