Wait, wait, wait! Did they say that they may decide to charge me in the future? And that they may reclaim the URL or remove it “for any reason, without notice”?
 
 A URL is an identifier. I’ll use it to identify myself on this service. I’ll link to it from my website. I may print it on a business card. Like Google said in their email, I’ll use it to “point folks to my profile”. But they can take it away for any reason or decide to charge me a (yet unknown) amount of money in the future?
