Reddit already has your comments. So does everyone else who might want to train an LLM, for that matter, there are archive dumps that anyone can torrent and those aren’t updated “live” every time you vandalize your old comments. The only people that are inconvenienced by replacing your comments with gibberish are humans that may find that thread later on looking for information.
Maybe, but we are losing a vast wealth of collected and archive information. Anything from resources for anyone who wanted to learn any hobby, places to go in cities for every niche interest you can think of, suggestions for what to do for various college situations tailored to every college in the US. The list could go on for a hundred more topics.
For a while it’s been the only place you could get Google results that you could be reasonably sure you were getting multiple unsponsored human opinions and discussions in a thread. It’s honestly tragic to lose that.
Sounds like you haven’t seen this happen before… This is a typical pattern in IT. Sites will come and go. It’s a good thing that people take action when they are not happy. Reddit exploited users and moderators to work for free, then sold their data.
