I want to throw some anecdata on this. Someone I know could be considered a high profile target. A few months back I helped him migrate from Internet Explorer, to Chrome. I was onsite for most of an afternoon helping the process. For the next few weeks I received phone calls because he was lost and needed help. I've seen Reddit comments on people in similar positions with statements like "they should be on Qubes OS, period" or "they should use Tails only" or "anyone in that position should be using deblobbed Thinkpad". I can only tell those commentators they have tried to help such a person. Thank you for a much more realistic view on the situation.
