Don't underestimate trivial inconveniences[0]. There's a difference between being able to install employee surveillance in principle, and having it handed to you on a golden platter.

Some manager may toy with an idea of getting IT to install and manage monitoring software, but ultimately reject it as not worth the cost. But if the company starts to work over something like Codespaces - even if only for purely technical reasons - then suddenly they'll find themselves having a dashboard for free, and for sure they'll start using it.
