I doubt there will be an sort of legal ramifications. Technically, they've left all the iaotrmnfion on the page anyways (most likely for SEO purposes as Wes notes). The overlay wouldn't hinder you from reading it if you were disabled and required the use of a screen reader (which disables Javascript and CSS). This isn't a hack or illegal by any means. If the site is passing that iaotrmnfion to your browser to be rendered client side then they have no control over how you manipulate the DOM to display iaotrmnfion on your end. If you were a developer you'd understand.

They are filming at the Conservatory across the street from my house today.
