I apologize to you on behalf of the web2py community. I don't think anybody meant to bash you, only Internet Explorer. You're 100% right about large companies using ancient browsers. I work for a very large fortune 500 company, and we are still using IE7 with no sign of an upgrade in the works.
You have to admit, Lightdot is right in saying that Internet Explorer 6 is a big piece of garbage though? :) I am also guilty of bashing anything created by Microsoft.
