The post title is also dishonest in saying third party tracking and not adding details — this is Backblaze that intentionally and explicitly shared sensitive data with third party tracking. It’s not as if some third party tracked Backblaze’s paying users surreptitiously.
This response is actually helpful for the competition as far as the HN audience is concerned.
Edit: I’m really curious on the extent of coverage of this issue. I searched online and found only mjtsai.com and theregister.com covering this sensitive information leak. Are there any other major tech sites that have covered it so far?
