I was coming to say exactly this. This is just a criticism of someone not familiar with the Mac ecosystem. I use Moom myself and it's been perfectly adequate for my (Macbook) needs.
This isn't exactly rational, but something about having to install amphetamine to disable system sleep really set me on edge about the MacOS ecosystem. It just felt kind of aggressive: like Apple wanted to ensure that I had somebody other than them to blame for a dead battery, and they wanted this so badly that they removed functionality that is a system setting literally everywhere else.
It made me afraid to let this MacBook contribute to my "for problem W on platform X use config Y on app Z" problem any further. I can't put my finger on it precisely, but something about Apple's design decisions makes me uncomfortable.
