If you are a remote work company and hire someone who is not passionate about what they do, they will, for certain, take advantage. And why wouldn't they? So it is easier to just lean on the side of caution, especially if the management chain isn't entirely on top of things (which is common, because everyone is busy).
In an office, “being there” becomes a proxy for productivity, even if it’s not accurate.
Once you remove that, the gap becomes very visible, and instead of fixing measurement, a lot of companies just revert back to what they’re used to.
So it ends up looking like a remote work problem, but it’s really a management/measurement problem.
