This is speculation:
I think a lot of it is temporarily leased or loaned. i was watching a retrobytws video recently, cant remember the exact name. but it was about this console that was ‘designed for girls’ (read what old men in suits think teenage girls want). He said a lot of.yputubers have made videos on it, but console is actually pretty rare. One or two people own pne amd loan it out to others for their videos.
Also auctioning. I gotta imagine some of it can be flipped.
Maybe donated to a museum.
That’s just me speculatong tho.
tbh you should prolly use pgrep instead of piping ps into grep
