The Wikipedia article has these relevant quotes from the court opinion:

The question is thus whether the Betamax is capable of commercially significant noninfringing uses … one potential use of the Betamax plainly satisfies this standard, however it is understood: private, noncommercial time-shifting in the home.[7] […] [W]hen one considers the nature of a televised copyrighted audiovisual work… and that time-shifting merely enables a viewer to see such a work which he had been invited to witness in its entirety free of charge, the fact… that the entire work is reproduced… does not have its ordinary effect of militating against a finding of fair use.[8]

In 1984, this issue made it all the way to the US Supreme Court, which ultimately decided that recording television to tape using a VCR for personal use (“timeshifting”) is fair use: https://en.wikipedia.org/wiki/Sony_Corp._of_America_v._Universal_City_Studios,_Inc.

Alpine.

I’m a longtime Arch user, and would have preferred to use Arch on a particular system, but didn’t want to deal with needing to babysit ZFS packages from AUR.

So, I decided to use Alpine after never having tried it before, and ended up sticking with it. Like Arch, it’s both lightweight and has a capable/sensible package manager, which are the main things that are important to me.

I haven’t had any growing pains from Alpine’s use of busybox/musl/openrc, things mostly Just Work!

I self-host https://miniflux.app/ and it has been working great for my needs.
