For one I don't use software that updates constantly. If I had to log in to a container more than once a year to fix something, I'd figure out something else. My NAS is just harddrives on a Debian machine.
Everything I use runs either Debian or is some form of BSD
Why is it so hard to send large files?
Obviously I can just dump it on my server and people can download it from a browser but how are they gonna send me anything? I'm not gonna put an upload on my site, that's a security nightmare waiting to happen. HTTP uploads have always been wonky, for me, anyway.
Torrents are very finnicky with 2-peer swarms.
instant.io (torrents...) has never worked right.
I can't ask everyone to install a dedicated piece of software just to very occasionally send me large files
