Concerns about cheating from?.... Folk who give games development a bad name. Their "concerns" are moolah, not the gamers or the games. I've my doubts about this Steam Machine; the likes of Minisforum will clean their clocks with twice the storage and RDNA 4 in the medium and long-term. Steam OS as Messiah Linux Distro on the Desktop is much more interesting than the hardware. Various of your leading distros are forming circular firing squads and making a fair stab at self-deletion just as Micro$oft Windows is making a fairer one.
Edit: I've seen more extensive coverage and my doubts have receded quite a bit about the Steam Machine. I still don't see it as a threat to PC... but consoles? I might like the smell of Steam in the morning; it might be the smell of VICTORY. The Steam Frame VR; the Steam Controller & Steam OS I'm all on-board with them: if they've called this right, I see thru the mud and blood; the green fields beyond.
