Malls were dying in the US well before Amazon and online shopping itself was meaningful. Big box stores did a number on them. Best Buy and Circuit City had nearly the same selection of music that mall music stores did for much lower prices. Stores like Barnes and Noble and Books-A-Million eviscerated the smaller more expensive mall book stores. Walmart, Target, and the like hit everything else.
Once that decline happened, I noticed that many malls started going after the kids that just hung around malls and weren’t in constant spend mode. Teens were treated like pests that were not wanted. Guess who got the message and didn’t come back a few years later when they had jobs and money?
Malls in the 80s and early 90s were pretty awesome, but malls told us to fuck off so we did. They can rot.
I’m not sure I consider myself a “veteran” since I still used Windows most of the time back then, but I used it in the late 90s. This is all anecdotal from my perspective, but the late 90s Linux experience was pretty rough on the desktop side, especially installing it. I actually rarely saw Debian in use, it was usually Red Hat for the sane people or Slackware for the lunatics. There were a few notable Linux game ports, but generally speaking, gaming wasn’t something most people did or even expected to do in Linux. I think I had a small handful games that weren’t terminal roguelikes: Doom, Quake, Tux Racer, and Alpha Centauri ( this one might have been early 2000s, hard to recall ). I can’t say I personally saw anyone openly using it at the university level in almost any form when I attended, I saw a lot of Unix though. Everyone I knew that was using Linux was younger and did have a slightly hobbyist leaning, with the more serious people usually using OpenBSD or FreeBSD.
