The point is that you can't do this with notebooks though, seems silly to want to do this here, with maybe the exception of blocking sync services you can't monitor. Which is totally possible with a bit of competence.
Though is, 'you also cannot do this with a real notebook' valid argument? Neither can you upload pdf's to a real notebook or do all the other stuff that makes this device not just a ... regular notebook.
Exactly. A paper notebook might not have those security features, but it’s also a lot harder to end up with reams of confidential info in a paper notebook in the blink of an eye, on a whim; or to transmit that data to arbitrary third parties. There’s a “proportionality” argument between features and security.
