Biased as fuck lol. Installing windows is not difficult. I did it first time at the age of 8 witn WIndows 98 and their newer installers are made so the general public can do it. And the bloat and spyware? Thats windows dude. Its not meant to be your OS, its meant to spy on your ass at the benefit of being familiar and (relative) easy to use. Anything you do to it post clean install is your own tinkering. Linux distros are great yall, but install difficulty is not a metric I would use to attack windows. Comparing between distros makes sense.
What is interesting is that streaming gaming has not filled this market space and on device processing is still more favorable. If you think about it the ps5 streaming controller thing is already a portable ps5, they just have to move the processing to their servers. If anything, this tells us streaming is just not there yet for the vast majority and portable consoles will continue to do their own processing for the foreseeable future.
