QUOTE: if anything, the choice of quotes seems to be aimed at putting Mark in a bad light (very few articles have this many direct quotes)
It's impossible to know if the choice of quotes is aimed at anything, or is instead a fair representation of the interview. That's why journalists often keep a recording. Given Jake's previous reporting it might be fair to assume that he managed to capture the essence of the interview and in order to reinforce his interpretation provided quotes to anchor it.
If you look at the companion piece about UDS you'll see that the same style (short, inlined quotes) is used.
