“Microsoft Tuesday confirmed the bot’s potty mouth and snipped Santa’s Web connection.”
The bot was just using the language that was input. Thee are plenty of reason to bash MS these days but I fail to see how this is one of them.
Apparently the bot actually did initiate the reference to oral sex- seems these kids figured out that if you ask it enough times about eating something (in this case pizza) the script generates that line all on its own.
