And here's the huge thing about 6.0 that people forget: during those days, we almost always (in the US and Canada at least) saw only the top skaters. We didn't see how low the scores typically could go. I remember that one Ultimate Four where Kurt forgot the last 30 seconds of his short program and just went in circles trying to remember what he had done, and he had scores down to a 2.5 or 2.9 or something technically, which I thought was

simply because I had really never seen a program scored that low, or if there was an off-chance that I did, those scores were from someone much less known than Kurt Browning.
(ETA- completely random side note but I remember Fedor Andreev blowing all three jumping passes at 2001 Skate America, ESPN still deciding to show him and constantly remind us that he was an A&F model, and he got scores down to 2.5 or so, too, and I remember people talking about that like it was a surprise as well. I suppose it would've been the first instance of fans that joined around the time of Nagano seeing scores that bad.
When you're only seeing the top set of skaters, the marks make more sense because the judges are likely comparing those skaters to one-another. And it's not like the judges didn't get creative with their second marks, anyways, especially in short programs. That way, they were still capable of sliding a favorite or top contender exactly where they wanted them to be by simply saying 'but their presentation was stronger'.
As far as the last point- this is another thing that I don't understand when people complain about the lack of skating. I came into watching skating in 1993 and recorded everything in sight from about 1998 until I left for college in 2004. Yes, ABC and ESPN were getting to the point of showing 6.5 hours of Grand Prix events a week. But besides those, Nationals, 4CC, Euros (which those two were just the final groups of the LPs, anyways), and Worlds, we didn't see anything else. And the majority of the stuff was on tape delay anyways. Now we see every skater from every competition, even obscure National Championships via YouTube. Popularity surely went down in the US and I'm sure it took a huge hit in Canada following their entire top team retiring after 2018, but it's thriving in other places and many countries now at least have the chance to see skating to begin with. I don't even think Europeans typically saw anything besides Euros or Worlds and the occasional Grand Prix until about 2002 or 2003 when streaming options/video sharing became a thing.
