It would only be a legal issue if folks didn’t give their approval. I am saying Plex should collect this information after getting user approval and sharing it if the user approves (either with their name or anonymously). And I don’t mean details on the content (like what media users have) but rather their server/system/storage configuration.
Don’t think you understood FordGuy61’s reply. They already collect such information:
Paragraph L in privacy-legal:
