Kate is probably getting too much attention, in their eyes, and they expect to be front and center for their grandmother’s 70th anniversary or funeral, whichever comes first.

Big whinies.
Grandma didn’t invite the the Markles to her Jubilee so this is his excuse for not flying over. Not being able to attend will mean they can’t fulfill their obligations to Netflix and Spotify.
