This isn't about Konami wanting spoilers to get out and ruining the story (besides, it didn't only cover the story - the embargo also covered install times, which is a major gripe for many on the PS3); this is about review embargos that publishers demand on review sites and how, lest said sites obey their demands, they are blacklisted and refrained from receiving copies of games to review in the future.
This is also about EGM / 1up not bowing to pressure and how it's the "right" thing to do. It's not about production values, poker tables or promotional posters decorating the set. Hell, if that were the only criteria to credibility we should all watch - and believe in every word from - Fox News. They have really good studio sets.
And... their opinion is just as valuable, invaluable, or useless as forum posters. You learn to weed through the good and bad commenters. I thought these guys had a valid point, and it was much less about MGS4 than it was about embargos, review censorship and journalistic ethics. I think you missed the point by a nautical mile.
