Actually, nothing has changed. I remember the release of Falcon 3.0 quite clearly. Dec 7, 1991. Easy date to remember for obvious reasons. 
The Falcon forum on Prodigy was one of the few places that existed that people could talk about it. There was usenet, but that was fairly niche, and Compuserve, but that cost $$ at pay-per-hour. So a lot of people went to Prodigy. We all stayed until it went pay-per-hour in 1993 I think. 94?
The vitriol there was ridiculous. That game did have some legit big issues, like the 5.25" disk version did NOT install. If you bought the 3.5" disk you were fine, but the 5.25" was busted. Of course, the game itself had bugs little and large.
I learned then that many people just don’t get it when it comes to posting online. While some of us use the nuances in language to try to convey our feelings accurately, others have the subtlety of a sledgehammer on a Lego set. There was one guy there named Tim, I don’t recall his last name, but he would regularly post these Denis Leary-style rants, except they weren’t humorous to anyone, just nasty.
I met him a couple of years later in Las Vegas at the Fal-Con the forum held. He was the most soft-spoken, timid, doughy, unassuming person you could meet. There was zero correlation between his IRL persona and how he acted online.
Bring up the issues in F3 and he would talk calmly about how SH needed to address this or that problem because it was causing a domino effect with others and such.
Yet in the P* forum the way he posted would make you think he was frothing at the mouth, hateful, irrational…
He just never understood the concept of a mic drop. He wasn’t going to make his point and move on. He was going to make it in every thread, in every post he put up, every day, because he apparently believed that was the only way to be heard. Flood the forum with his complaints. It was like he both didn’t see his online behavior as wrong, because it was virtual I guess, and he also didn’t comprehend how he came across to others. Without the visual and auditory feedback, he just screamed into a void and hoped it came out as a whisper.
Today there are even more people on the internet than there even were with PC’s back in 1991. The average intelligence of that online population is obviously lower as generally the stupid weren’t paying $3k for a PC in 1991 just to bleat online. Today you can get a cellphone or even a cheap PC for $200 and let rip. So if the averaged more intelligent online population in 1991 was not all well behaved than there is no doubt in 2019 it wouldn’t be any better. It’s still about 10% of the people, but now 10% is like 10 million people instead of a few hundred.
