Did Jagger or Richards speak out about the whole thing given their financial interest in the outcome?
Nope.
They had NO financial interest in the outcome. Their former managers own all the rights to that song. Allen Klein owns the publishing rights. Andrew Oldham owns the performance rights since it was his orchestral version that was sampled. Do you really think the manager who screwed them out of their songs is going to give a damn what they say about it now? If anyone got shafted it's Mick and Keith who don't get royalties for anything they wrote before 1970.
