well kurt was a crazy heroin junkie that had attempted suicide before, that being said questions still remain surrounding the investigation. foo fighters had some quick success with their first album, (dave recorded all the instrumentals and vocals himself, there was no foo fighters when the first foo fighters album was made.) but it was only because of his ties to nirvana. foo fighters put out a lot of albums and did a lot of touring after that first album and built a fan base the old way. nothing was handed to him imo.
if anybody was going to sacrifice kurt for their own gain it would have been the women that started her career as a 16 year old stripper in japan. how else do you think the biggest junkie in hollywood survived passed 27?
