Clear "Correlation does not imply causation" case. The fact that people stayed more time at home implied they consumed more of everything online and accelerated digital services adoption making companies related with digital services sell more, plus less expenses (no travel, less expenses in facilities) made higher profits. Remote work correlating with Higher profits is a correlation not a cause afaik.

Not trying to be nitpicky but that sounds like actual causation. I would describe it as a second-order effect.
