In addition to the other comments here, we can’t rule out the human love for hobbies either. Did I spend 2 days hand coding an entire blog that I won’t show to anyone just for fun to learn some HTML and CSS? Hell yeah I did. Will I use that knowledge to make something less chaotically coded that I can actually be proud of? More than likely.
Obviously that won’t be a large percentage of the market if even a noticeable one but, I’d like to think hobbyists will help preserve some good open source projects.
I have to overhaul that one it’s not very readable. Like the code is garbage but I did make https://sims2anin.neocities.com/ last week. No blog feature yet, just custom content I’ve made for the Sims which is my current ADHD hyper focus.
