Probably for the very simple reasons of convenience and wanting to use a mobile device to communicate? A clunky laptop with low / no state is not that. We all know 'it doesn't have to be this way'. There is nothing special about your personal OS needing to phone home on you. I think people are more likely to use something like LinageOS vs something like tails if they want 'more secure' communications than to drag a laptop around with Tails.
