But you're right, as long as everything is working normally, working on premises slows you down to do maintenance, updates etc etc. Cloud (of all kinds) takes that work away and you can work faster. And in the VC-driven daily and eternal grind, moving faster is the only thing that matters.
You could just block most of the internet services - gmail, youtube, facebook etc under these rules, and then wreak havoc. I bet they'd roll back these laws in record time if someone pushed them to the limits :/
