Does the archive team ask permission from users before crawling data?
If you put a website and don’t set up a robots.txt file, does it still get indexed by Google? IOW, isn’t it “opt-out”?
If you ever posted a question on StackOverflow, did you have to give explicit permission to have your data pushed to their data exports? Can you ask to have it removed?
Google gets (rightfully) a ton of shit when they violate users privacy. What “privacy” is being violated here, when the data is on a public network and it can be crawled even without access to the API?
