It looks as though after 3 months of constant complaints Groundspeak & Google have patched up their differences and we are back with Google maps, at least for Premium Members. I can find no announcement of this, it just happened last night. There is also no mention of this on the Groundspeak blog, but they are advertising Google maps as an advantage of Premium Membership. I guess we will now see a hike in membership fees. Strangely enough, when using Internet Explorer it does NOT state that you a using Google maps, but Firefox does.
However, this change by Groundspeak seems to have blown our Greasemonkey scripts and I can no longer get the OS maps, just Google maps!
