Not sure why you’re getting downvoted. The only time I use the power button is when there is an issue which has been like 4 times in 3 years maybe? I think people complaining about the power button location have never worked with macOS and are used to shittier standby in other operating systems.
The default web interface is very poorly designed and looks uninviting. Sure, there are great alternative interfaces but people will be turned off before they could check them out. Also, it’s usually the first thing you see when someone’s sharing a link.
There not being an official app is also something that will confuse non-tech users.
