I work 8 years on Upwork and I only work with this feature. Initially, I was hostile to it, but later one “accident” helped me to realize the whole purpose of this feature: disputes. When client don't want to pay, they have 2 ways: 1) just don't put the money to the bound card account, or don't pay the bill; 2) try to say that the freelancer wasn't working. In both cases, screenshots are the protection for a freelancer. In the first case, Upwork just pays you their own money. In the second case, you have huge evidence that will help you in the dispute. About micro-management: in 99.9% of cases clients don’t check the screenshots. I saw how it works from both sides. Also, in 8 years I had 1 client who turned off the option of tracking time manually (you don’t get payment protection for manually tracked time, so you only do this when you trust your client). In comparison to never-ending hell in the fixed-price contracts, per-hour payment is the most comfortable way to work.
