No need for cynicism - the AC somehow turned into an account (It showed as AC for me too at first).
You're right, the walled garden isn't the thrust of what the politician was saying; I was just replying directly to the comment.
However, I think my point still stands - the politician doesn't like something about a device, but the specific issue he raises is a general concern about data security - not something specific to an iPad. As far as I understand it (not being a regular user of Apple products), if you were to install an IMAP client (Or use a native one?IDK) on an iPad and use that to access your email, then your data is no more or less secure than using a laptop (Linux or not). The abstract (at least - the article itself is badly translated), implies that the politician reject the iPad specifically because he felt it not as secure as an alternative.
As I say, my knowledge of Apple products is limited, and if you were to tell me that an iPad takes unconditional snapshots of it's entire storage (including third party app storage), and backs that up online then I would concede that it is less secure.
