I rarely use any kind of chat, but I used IRC sometimes back in the day. I was recently working on a thing where I needed to use Discord for some programming advice. I got the info I needed, but yeah that Discord is a convoluted mess. Newer hardly ever means better.
I’ve ripped a good number of blu-rays to network storage. If you’re looking for older, less popular stuff it’s the best option. And older releases are usually just a few bucks. The new stuff I torrent because I can usually find a decent rip, but for stuff I want to put in my library a rip from optical disk is the best, but not free of course. You can even do it for free, public libraries often have a good collection of older releases on optical disk.
