Setting the source and tone aside is crucial to any good analysis of a subject, so setting the Vortex source aside, I've noticed two things that seem to be relevant here. The first is that while Google is usually pretty good at blocking spam without false positives, it seems to be getting worse at that task, rather than better. Furthermore, it is notably bad detecting when an email is or is not a scam.
The second, more important, point comes at the end of the original note, and it's that Google as a whole has virtually no functional feedback mechanism for error correction. It is very hard to get any attention at all from staff, and even if you can manage it, my recent interactions simply yielded brain-dead responses and endless run around. This was with a botched Google Wallet payment where the firm sent confirmation saying "This money is now yours." but never delivered it. After many hours of investigation, there is still no real answer or means for progress.
Everybody gets things wrong sometimes, but Google seems has strayed a long way from its original "Don't be evil." motto. It now seems to do whatever benefits its bottom line, and costs the least without any regard for accuracy or allowing people to help it fix its mistakes.
