That one is a little bit worrying.

It appears they're saying you can't turn down updates and indeed there is no such thing as an update, you get the latest and livest version every time you fire it up.

In that case that makes their servers a stunningly tempting target and you have no protection from a nefarious party feeding you something unhelpful.

I get the feel they're trying to invent the wheel while barrelling down the highway and at some point they're going to miss something extremely gaping and obvious.
