Do you honestly think that no service out there collects basic analytics?
That doesn’t mean they are allowed to go beyond and scan user’s environment variables
What is the harm of that disclosure? If you are a company that wants to establish a firm basis of trust because you deliver a sensitive service, it is a necessity. I can't say with certainty that Anthropic doesn't disclose that they collect this info, but in any case, the way they've chosen to implement it does not lend credibility.
e.g. "Claude Code connects from users’ machines to Anthropic to log operational metrics such as latency, reliability, and usage patterns. "
