Managers who could only measure productivity by butts-in-seats are turning to surveillance software and always-on webcams to measure butts-in-seats at home. If you don't trust your employees and can't measure their productivity, maybe you are the problem. https://www.washingtonpost.com/technology/2020/04/30/work-from-home-surveillance/
This kind of patronizing remote control isn't limited to IT and management. Many tech companies, in the name of security, exercise the same kind of remote control over your computers without your permission. I wrote about the phenomenon here: https://puri.sm/posts/consent-matters-when-tech-takes-remote-control-without-your-permission/
@kyle and tbh even in former case the consent is given - when you receive your PC from the IT dep you sign the asset list which I'm pretty sure normally contains the consent. It's just no-one reads that (as any other digital license agreement).
