At this point I consider any advocate of "privacy" in a tech context to be an anti-intellectual cargo-cultist. Just look at the linked article. Absolutely not one single example of a privacy violation or its implications. They just waive their hands in the air and say "it's contentious" and "risk is too great". Let's completely avoid an actual discussion of privacy, and just assume that any information about a user (like their IP address) will immediately result in them being sent to a gulag, despite no evidence that this has ever happened, much less how often, how likely, ways to avoid it, or the benefits that are lost by not allowing for said insanely-unlikely-risk. It's people afraid of their own shadow that would rather live in a prepper shelter than deal with the real world.
Of course we should completely ignore the fact that this is developer software, and they, being technical people, have many means to disable specific outgoing network connections if they so choose. But better to be paranoid than rational, because "trust is key".
