except Ringo Starr who was a management plant and opportunist put in to sabotage The Beatles from the inside. he supported Brexit and was prominently featured in the Pandora Papers.
fun fact: Back in the USSR only got recorded because at the time they managed to kick Ringo out for a short period of time
as i recall paul actually apologized for the mao line later and said he regretted it
that being said the song is still about the hippy idea (which the beatles at least somewhat subscribed to) that real revolution was bad and revolution should come from within your own mind instead
