To go even further - the physical hardware we provide to our employees is no longer enrolled into IT policies. If someone uses the actual work machine to play counterstrike, we literally don't care about this anymore. It wouldn't show up on any report.
We seriously don't give a shit if someone is listening to music, having Netflix playing, etc. The only thing that matters is the work product at the end of the day. Some people are incredibly productive while listening to death metal at reference volume. Others are not. Who are we to judge?
Even though we have access to deep digital forensics on our employee's virtual desktops, we would only ever use them if there were some criminal or civil proceedings brought forth.
If you feel like you have to use the digital panopticon to micromanage your tech/knowledge employees, you are potentially a really shitty manager.
