Can't speak to the non-av part of the article, haven't had any issues like that to relate to particularly.
As to local AV stores, there aren't any where I live, and even in the small city nearest us (45 minutes away) only three. One is, a Best Buy (which doesn't even have a room for audio, just the main floor and not much gear either), a car stereo outfit, and one that identifies itself somewhat as an "audiophile" type place. I did drop in on that last place one day, and they didn't even bother to say hi to me; two guys, both on the phone, could barely make eye contact with me and certainly didn't ask whoever they were on the phone with to hang on a second and say hi and give me an estimate of how long it might be until they could help me. I waited a few minutes, checked out their messy and rather meager offerings and left with no desire to ever go back. They seem to sell used gear on craigslist, too. Not my cup of tea.
Now, I could drive another two hours to a bigger city that has a few audio stores I've read of (and even seen a pic or two of), and even a speaker manufacturer is there I wouldn't mind a tour of.....but that long a drive to shop for something I don't particularly need at this point doesn't make much sense. I've done fine shopping on the internet and don't mind supporting a few internet-direct operations as well as Amazon. When I lived in a major metro area (SF Bay Area) by the time I moved out there were few audio stores, and would entail a long drive generally from where I lived; it hadn't been like that 40 years earlier, but they slowly disappeared over the years.
