I never had a problem with Yoko, but its not her place to interject on Paul and John’s very complicated, tumultuous relationship. Or for the whole band in that matter.
John wrote many great songs to or about Yoko. His love for her was real. I can't imagine John in heaven being pleased by his fans still expressing their Yoko hatred.
How Do You Sleep was John's response to the song Too Many People in which Paul surreptitiously criticized John... And Lennon responded directly in a cruder way, as he was.
Utter bullcrap, it’s been noted by multiple sources that the catalogue was offered to Paul and Yoko and both of them were too cheap to buy the catalogue, which included music buy other artists.
