I check it one a week for ~10min to see hours logged per day and quick random to check its not loads of time wasting.
It feels intrusive but there is little difference than people walking past someone in an open plan office + they can turn it off anytime they want to do personal.
For me I see this as really useful for managing Jr remotes. And personally would have no issue running it if I was working remote. I think the pain points would be more about how management use it, and in its worse its little different from having a micro manager in a on-site office experience.
