I think it's a little more nuanced than "bands/producers don't care" and a bit more complex than "exporting the audio (that already exists!)".
Directly exporting the audio straight from the mixer would not necessarily produce quality recordings because the audio there is tuned for the purposes of sound reinforcement. To properly record a live concert requires an entirely separate setup with their own microphones and then some direct output from the mixer on a per channel basis to allow for post-production editing.
And a lot of people don't care about that! Lots of people are happy with the quality you'd get straight from a cell phone microphone.
But the people on stage and the people in the industry ... they're the ones actually involved in producing the sound, and many care very deeply about the quality that gets recorded and then shared. That's not to say that all musicians are like that, but many are!
No, there are actually four different punctuation marks, all which look remarkably similar to the untrained eye.
1. We have the hyphen, which is most commonly used to create multi-part words, such as one-and-one-thousand.
2. We have the EN-DASH, which is most commonly used to denote spans of ranges. As an example, Barack Obama was President 2009–2017.
3. Then we have the recently maligned EM-DASH, which can be used in place of a variety of other punctuation marks, such as commas, colons, and parentheses. Very frequently, AI will use the em-dash as a way to separate two clauses and provide forward motion. AI uses it for the same reason that writers do: the em-dash is just a nicer punctuation mark compared to the colon.
4. Lastly, we have the minus sign, which is slightly different than the hyphen, though on most keyboards they're combined into the hyphen-minus.
By the by, they're called the em-dash and the en-dash because they match the length of an uppercase M or N, respectively.
I feel the same way. I've used em-dashes in my writing forever, and I was always particular about making sure they were used properly (from a typography standpoint with no surrounding spaces).
But now, I have to be so picky about when I use them, even when I think it's the perfect punctuation mark. I'll often just resort to a single hyphen with spaces around. It's wrong, but it doesn't signal someone to go "AI AI AI!!"
