Its possible the danger is that if a fire starts near the stove, now it has plenty of oxygen supply. Would that have make a difference in your friends cabin? Maybe - Maybe not...
I agree some houses are so tight they need a dedicated air supply. The only problem is that it can't be regulated to deliver exactly what the stove uses, which would be fine in tight house. But in a not so tight house, it just makes for more additional cold air infiltration than necessary... There isn't gonna be a one size fits all solution with all the variables involved and people are gonna do what seems to work to them. Most of the conclusions in this thread are based on rules of physics, and to prove that the physics are working would require measurements that would be very difficult to obtain. So do what ya like
Things aren't always what they seem and sometimes things that look good on paper don't work out so well in the real world.. and I totally respect that
