I don’t think he had a plan in the beginning. These people aren’t pioneers. They got lucky once, get labeled as a trend setter and then you have to try and maintain that image. VR was going the next big thing, so Zuck bought a company without a plan. Tech companies do that all the time. They see themselves falling behind on something and just buy some random company to appease the shareholders/press.

The VR office thing was just the limits of Zuck own creativity and saw covid as an opportunity to keep their product relevant.
