To be clear that was 5 of the top 7 in the military not the CCP as a whole. Leaves just Xi and the anti corruption officer.

But yes agreed. It’s very hard to parse what is going on from the outside.

My very uninformed read is that the people who were purged seemed already loyal allies to Xi but had more clout to disagree with him, while the new guys know they are replaceable. The PLA is notoriously corrupt as well so hard to say which of those purges were political control vs corruption based.

I kinda doubt the new guys are unambiguous though you need to be ambitious and risk taking to rise like that in the CCP.
