How does Anthropic justify blatantly ripping off another company's work like this, especially without credit, then keep on whining about "distillation" when they suspect anyone else is merely using the output of their LLM in ways they don't like.

The other interesting part of this is the amount of time and effort it took Anthropic to do this, despite the fact that they were just copying an existing design - 5 months and (from another thread) 7 humans... Why couldn't one of their coding models/agents have done this by itself given the detailed specification? It's understandable that an LLM can't design a system like this by itself, but a bit surprising that even given the design is apparently can't code it up by itself either (else why did it take 5 months!).
