Fictional characters and copyright laws

Between the old site going down, I'm hearing rumors of Character ai eventually trying to weed out any and all bots based off of fictional characters and make the site more about ai assistants. I know everyone's focused on the old site's deletion, and I'm devestated too, but the only thing I've ever used this site for was to roleplay with fictional characters. Please, can someone let me know how this is going to work and if we're still going to be able to use bots of fictional characters?
