Ask HN: If AI is good, why can't Gmail stop the following blatant spammer?

I get one or two of these a day at my selfhosted account. It's McAfee (which is funny, I'm Ubuntu Desktop), Norton something, Microsoft Office, etc. They always come in from random Gmail accounts. I've individually reported dozens of these the past year or two to Google, using their web form, that their abuse email response requires to be used.

Does Google not care people use their account system to spam people at other domains? If their AI is good, seems like they could filter these before they get sent, perhaps even detect abuse patterns of the abusers?

These all have a very similar format. I don't use SpamAssassin but I may have to go back to using it, to see if it can reject these emails.
