IMO I think this goes back to the Xbox One. Microsoft really shot themselves in the foot with its release. It required you have the Kinect connected (requirement later removed), no Blu-ray playback (fixed with the Xbox One S), still wouldn't let you install your own storage media, and when they finally released the Xbox One X with had 4K gaming it was a year behind the PS4 Pro. Whereas with the PS4 you could install whatever 2.5" form factor hard drive or SSD you wanted, they didn't make any huge crazy changes, and carried the same great gaming experience forward without forcing changes.
When the PS5 and Xbox Series S/X came about, the hardware inside is now virtually identical, so there really wasn't a question about which was "better" anymore. It became about what the platforms had to offer, and IMO Sony did it right with the PS5. They produced a cool console with upgradeable NVMe storage, whereas Microsoft produced basically a SFF PC with vendor lock-in firmly in place. Xbox had already lost the loyalty of those who loved the Xbox 360 (myself included) so why try going back to their walled garden when most everything and a lot of great exclusives were on the PS5, and most everything else can be had on PC with very few Xbox exclusives?
I bought a PS4 Pro solely because enough games were exclusive that I didn't want to wait for hopefully eventual PC releases to come out. Never crossed my mind to get an Xbox One. Nowadays I still haven't bought a PS5 mainly (besides getting older and not spending as much time gaming heh) because I have enough on my PC to be going on with, and almost every game that I really want to make time to play will eventually be out for it. If I miss something, eh, I'll get a used PS5 later. Maybe.
Dude let's look at some examples from just the good ol' United States of America.
Everything defying obvious science is either political, financial, or religious. So yeah, there are definitely campaigns against it, and there are WAY more examples than my tired ass cares to dig up right now.
