I would say that it might shed some light on Adreesen's view of the world. Snowden is a very polarizing figure and which side of the Snowden issue one agrees with says a lot about a person.
While reading the article I looked a bit randomly at two video clips of Andreessen to see how he came over and on both he seemed slightly nutty. The first was saying 'obviously he's a traitor' about Snowden which I'm not sure is obvious and the second on why not invest in healthcare he said 'Healthcare, Oh my God, everyone complains that robots are going to kill all the jobs' which I think is inaccurate in that few people complain about that particular issue. It makes me take his views with a pinch of salt.
It's relevant because Marc is very influential and wields a lot of power in the tech industry. What he thinks about someone who blew the whistle on unconstitutional mass surveillance programs of epic scale is pretty important.
