Privilege isn't an issue with Claude (generally).

Maintaining privilege depends on taking steps to ensure the continued confidentiality of the data - put a lock on your file cabinet, sign an agreement with the vendor where they promise not to look at or use the data for their own purpose.

Even if hacker news thinks that agreement isn't ironclad doesn't mean privilege is or should be destroyed. It's more about whether you limit the distribution of the data in a reasonable way. Today, zdr remains reasonable.
