I know at the very least that you can get around Bloomberg's with Firefox's equivalent of Incognito alone.

incognito doesn't allow cookies to be stored after exiting incognito, so in fact it does allow you to read as many articles as you wish simply by closing and re-opening the incognito tab. As another poster noted, FF incognito doesn't track cookies across tabs.

I get around Bloomberg's using chrome incognito whenever I'm past 10
