Be it that they don't trust them to have the right idea, or trust them to do the work. Nearly all business practises we hate are caused by a measure of overt control over your daily time and a strict measuring of your time and tasks.
Unfortunately: there's about 10-20% of people who genuinely shouldn't be working because they are untrustworthy, and things like remote work just enabled them to take multiple jobs or slack-off massively.
So these practices mostly exist to deal with those people and the rest of us just suffer.
