RSS-Librarian is a read-it-later service for RSS purists. You can store articles from the web in your own personal RSS/Atom feed and use your favorite feed-reader software to read your stored articles later. RSS-Librarian uses no database and works without accounts.
True, this has happened with other similar sites before. The difference as I see it with Invidious is that it is an open-source project [1] that anyone can host. If the main page [2] goes down, you can divert immediately to an alternative host (take [3] as one example). All my RSS subscriptions are one search-and-replace away in my OPML file.
I can also recommend Invidious [1] as a Youtube replacement. It's effectively a proxy in front of Youtube, only loading the source data (i.e. the video) in its own container. You can subscribe to channels via the builtin RSS functionality just like on Youtube. I use a redirector extension [2] in Firefox to automatically redirect any Youtube links to Invidious, since the signature for loading videos is identical.
The whole free will debate always falls flat on its face because the distinction between free will and free choice is never made. You may not have free will, but you have natural tendencies that you gravitate towards. However, these can only be expressed if you have the choice to do so.
There is a joke that I think captures this philosophy of Compatibalism quite well: A reporter asks a citizen in Pyongyang to comment about life in North Korea. The citizen answers "Well, I can't complain".
