Cooper Markets

Just finished watching the video of zoom in the afternoon. After reading it, I was a little surprised. This is obviously one of the founders of MAM. Why do you say that he is just a market leader and investor in zoom today? Is it clearing the relationship?
Now MAM seems to be trying to disassociate themselves so that they can get off the car, right? Is this concealing something? Is it true that MAM and CPM are actually a group like the rumor, and they are all acting for us stupid investors?
