If you don't have people cheating with your malware installed (which you don't actually have evidence for), the literal only possible explanation of that is that no one cares enough to cheat properly.
Using a video camera pointed at the screen to control a mouse and keyboard that are exactly identical in every way to a real mouse and keyboard is not hard to do and no level of rootkit can ever under any circumstance detect it. It's unconditionally impossible for their malware to detect any mildly sophisticated cheater.
There isn't another viable option with just the performance/battery life combination, before even considering the excellent build quality, etc. Repairability has a major cost to space. They're in direct conflict. You can't do the form factor and have user repairable parts.
Buy a giant, bulky laptop that still can't match the performance for a full day of use if you want, but there isn't anything even in the same space as the Apple Silicon MacBooks, let alone competitive in that space.
