2. There are young and old people who will have trouble understanding another technology.
IMO, this is a complete non-argument. You don't need to be an MCSE or similar to understand how the magnet links work. Age is no argument for or against anything. Well, except when it comes to medical issues and similar, then yes. But when it comes to technology? No. There are tutorials, help files, instruction manuals, etc. If you don't use them, well, that's your own fault. I'm sorry, but I've worked in tech support in the past and most of the stuff people came to the hotline with could have been solved by reading the bloody manual and using the brain.
Also, if you're a young person having trouble understanding another technology, then you live in the wrong era. And old people can adapt just as easily. My mother is over 60, she's not tech savvy, she's no engineer or technician, she never had any technological training, and yet she has no issues with operating even new technology. What am I saying. Operating? Try installing. She just switched from a VHS VCR over to a hard disk recorder. Set up and installed everything herself. She knows how to work it. My father, on the other hand, is lost with the system. Why? Because he doesn't really want to sit down with the manual and learn how to operate the new system. He's just lazy. Somebody else will take care of it.
But as I was saying, age is no excuse. And being lazy certainly isn't either.
Oh, I know what you're saying. I'm now too harsh and probably "offending" someone (my opinion about "being offended" is the same as Stephen Fry's.) I counter with this: technology advances and our politicians are getting dumber and more power hungry all the time. So we need to adapt both ways. And you either adapt or you're left behind.
The VHS is effectively dead, are you going to complain about that too? Bring back the VHS cause you can't be bothered to learn how to operate blu-ray? Really?
5. Too many reuploads would make DA be like a "pile of rubbish for useless torrent threads"
Another non-argument. Go ahead and try downloading a specific episode of a random drama from 6 years ago with the normal torrents. Good luck finding a seeder. It's extremely likely you will be sitting at whatever random % for years. With or without the old torrent system. Reuploads happen all the time. Usually old dramas which then come in batches.
