It's great this employee was able to find another remote job that hired them. That is how the market will sort these things out. If there is really no advantage of having people come into the office, then companies that require it will have a smaller pool to pull top talent from than employees that allow remote work. On the other hand, if there are advantages to collaborating in person the companies that get people back in the office may have a competitive advantage. The culture that has grown up around remote and hybrid work in most companies is bad enough for collaboration that I bet we'll see some companies doing much better with people in the office. This isn't really because being in the office is more productive, but doing remote/hybrid poorly is worse than the average way of doing in-person work.
