Pertinent to my earlier post about google tracking your location

Is this article from El Reg.

Also as a matter of interest. I noticed that after I visited the myactivity.google.com site, without making any changes to settings, the blogger app stopped working on my phone, requiring me to enter my password, which was rejected as 'pattern unrecognised' each time. The phone had clearly remembered my google account settings (I could access gmail) and the only fix was to delete and re-install blogger.

I suspect this is probably a legitimate concern, both from a personal and governmental standpoint.
