This is a good example of why post summaries are considered off-topic on HN. If it becomes the top comment (which it often does if people agree with it or are riled up by it) they'll reply to the summary rather than posting their replies as root comments to the main thread, creating a split between replies to the top comment and root replies.

Also, please don't use a title for the HN submission that's different from the title of the original post. The guidelines are specific about this.

Can you confirm that the title is correct and that it encrypts rather than hashes?

Both are concerns, but sending interpretable data is a more serious concern.

I scanned through the article and did not see an example of the header it added.

And certainly fingerprint you right?

can, but how? Have you verify all 6278 and what they do?
