Was this "death" the one where Marvel killed him off and replaced him with his daughter and was gonna try and act like he never actually existed or something?
While I enjoy the spoils that come from the comic world, I can't say I keep up with it much. However, I have a friend who does and we chat about the comic world from time to time. I have a foggy memory of him saying something about Marvel randomly changing their characters (their race, gender, etc.) to make their comics more inclusive or politically correct with modern ways of thinking...
...if what he was saying was true, was this part of that movement?
No, this actually predated that by a little. Marvel essentially felt that Wolverine's popularity was beginning to smother other lines that they were trying to market at the time, so they took him out. I thought it was a pretty good storyline, actually. This decision was also made a lot easier by their ongoing spat with 20th Century Fox over the X-Men and Fantastic Four film rights and associated characters, which was also the origin of the
Avengers Vs X Men plotline 2 years ago, as well as the gradual diminishing and Bus-Boarding of the Fantastic 4 (they're barely present at all in any of the current comics).
Marvel wants to buy their film rights back, and Fox has refused to play ball. Marvel has offered co-film rights like they did with Sony, Fox refused. They offered huge lump sums to buy it all back, Fox refused. So as a last resort, Marvel is now attempting to deliberately devalue the properties so that Fox won't want them anymore. It's inspired, but also petty.
Fortunately, this hasn't really affected
Wolverine, as the writers are handling X-23 pretty awesomely in the role, and
Logan pretty much wrapped up the hugely popular 20th Century Fox iteration of Wolverine, so it's not really a "threat" to Marvel right now.
