Certainly possible. I personally think he's acting like a buffoon and I haven't been shy about stating it.
However, as I told another commenter in this thread, I think the relatively objective argument is that while Musk was necessary initially to get Tesla into existence and functioning, he's now more of a liability than an asset. It's not that he was never valuable or never deserved any trust - rather that he doesn't deserve it now.
Put another way: At what point does the goodwill he's earned expire?
