I'd bet that most people who care about this issue are primarily worried about losing the Wayback Machine. If that goes away, a lot of internet history will be lost forever. All those copyrighted works that IA was lending out won't disappear in the same fashion -- they will still be available from other sources.

IMO the Wayback Machine has always been the primary product, and most valuable part, of the Internet Archive. If IA wanted to do other things they should have done them via a separate legal entity to protect the Wayback Machine.

You'd be betting wrong. Even a casual skim of the Archive's blog will show that the Wayback Machine isn't their primary focus, and hasn't been for ~20 years. It may be their most important aspect to you, but the Archive is comprised of a large network of people working together to make all kinds of information available on the internet that wouldn't otherwise be accessible. To those people, those repositories are far, far more valuable than the Wayback Machine (and I promise they care a lot about this issue -- possibly more than HN does, given the timbre this topic has received here).

There is nowhere else that you can browse for example a Byte Magazine from 1984 (https://archive.org/details/byte-magazine-1984-12/). This is what the Archive is about, from their perspective -- along with music, video (including broadcast video), and a whole lot of other projects: https://archive.org/projects/

What I'm saying is that the things the people who work at Internet Archive care about may not be the same as what end users care about. I think the end users care mainly about the Wayback Machine.

The Wayback Machine accounts for about half of archive.org's pageviews.

You think most other people mainly care about the thing you mainly care about. Happens all the time.

it looks like the wayback machine accounts for more than half of archive.org's page views [1], making that poster's hypothesis correct
