Not a Mark fan but the Meta Quest Pro and Oculus are great and innovative devices. The obvious flaw in Meta business execution is that there is no content there! If you bet on the Metaverse you should build it and not wait developers to come. Or incentivize developers to use your platform.

From the business perspective I think they failed in playing the Japanese console game old strategy (Nintendo and Sony): work obsessively to have great and high quality content and synchronize this with the console launch. Not saying that Nintendo and Sony are not nightmares for producers but they are very obsessive about details.
