That dude is a bit of an ass, but I'll make two concessions...

Bad adventure games are really bad, true. Pixel hunting and verb guessing and odd sequences...

So really I mourn the death of good writing in games, especially comedy. Adventure games aren't the only source of good writing though, nor were all adventure games well written.

But there is still a dichotomy, because you cant have an adventure game without at least trying to write a story, but an FPS can just be quake.
