If it is doing this for all .com addresses I would think that this would be a considerable financial loss from revenue for wordpress. (my site is for victims who have been abused by sociopaths so a warning saying that the site is unsafe and could extract personal details etc - is not good at all).
I am unsure if this is a new thing for google,(it wasn't there or a problem previously as I often typed what I wanted into google and found my posts no problem) and if it means that I will need to move from wordpress.com to wordpress.org - I hope not as I tried that before but didn't like self hosting, using wordpress.com has worked well for me.
