I'm quite confident this is what any kind of WFH arrangement is going to look like for most people, in the near future. Some segment of the Tech Elect will not have to suffer it, but most people will, including programmers (most of whom aren't in FAANG or fancy start-ups or finance, and hell, some of those might resort to this kind of thing, too).
Whose to say this is solely applicable to WFH? Given the numerous anecdotes about how much time is spent at work socializing, I don't see how companies use this to monitor remote employees, but don't start utilizing this for those coming into an office.
I think it’s inevitable. If the software naively measures keystrokes or idle time, there are obvious ways to trick it. Unfortunately less technologically adept employees might not be able to circumvent it
