IIRC Crunchyroll used to be a pirate site so that may be where you heard that? But they’ve been legit for years.
I would say just look for x265 (HEVC) webrips of your favorite content and throw it on a Plex (or Jellyfin if you don’t have any Apple stuff) server. On the flip, if you have all Apple tech, Infuse is a good option, but IIRC it doesn’t stream outside your network like the other two do.
Because they want to stop people from using ad blockers.
