Security academics, self-taught pentesters, and people who simply gained hard security experience in their day to day jobs each bring something unique to the table. I'm far more likely to pick up the principal engineer with a security MS for a security architect role than I am someone who can prove to me they passed an OSCE.
That said, for the person who can prove to me they passed an OSCE, I'll knock two years off the pentest experience requirement for any such role.
So my comment was mostly trying to illustrate that the skills one learns by going through these kind of challenges are extremely useful in practice and the skills one learns by doing an Msc of the sort advertised here pretty much completely useless, assuming one wants to do reverse engineering and vulnerability research and not just push paper, point at his Master's and call himself a "security expert".
