If I create a new torrent, does CGNAT (carrier-grade network address translation) prevent me from being an initial seeder of that torrent?
It's not ideal, you won't be able to seed/upload to any other firewalled (non port forwarded) peers.
But technically any connectable (port forwarded) peers connecting to you will still be able to download from you, so you'd still be able to seed in that sense. That does mean you're only initial seeding to peers that have their own ports open/forwarded.
I can download and upload in my torrent client just fine, so I know my ISP isn’t (intentionally) blocking and firewalling torrents.
Yup that would work fine, you can participate in torrent swarms that contain other connectable peers and that's usually how most torrent swarms are. You'll probably have trouble with the random low seed torrents e.g. a torrent with one lone seed who also has no ports open, that seed won't be able to send you any torrent data.
My Sony Trinitron served me well back in the day - But no, I don't miss the CRT era. Just too huge and heavy. And honestly I don't remember the generic non-Trinitron CRTs being anything special, they were kind of shitty.
Anyways I thought the CRT thing is just collectors/old school gamers looking to display older media on a proper CRT? Obviously people with a lot of space, garages, basements, etc.. people in tiny rooms and apartments need not apply LOL.
This whole article seems a bit off.
