Or the title could be: "Big brother LA school district finds that kids are smarter than the geniuses who set this up".
Why would the LA School District care what the kids do on the iPads? Get a clue, the kids can surf from other devices too, and blocking it is just stupid.
Ok - I'll put this scenario into something that might make sense to you and others.
Your company issues you a laptop. They have security measure to block copying files off you computer and visiting certain sites because they are security risks involved and/or they don't want you goofing off on their dime.
Now you figure a way around it.
Should your company care?
Yes.
The iPads here were issued by the school - they are not owned by the students. If they want to block access to apps, websites, etc - that's their right and privilege. It doesn't matter what you do on your own device. And the LA district I'm sure isn't so stupid to think they can control what happens on OTHER devices. But they can on theirs.
