If I want to read https://www.washingtonpost.com/opinions/2020/05/19/post-american-world-is-now-full-display/, I have to use archive.vn which allows me to go past the paywall (https://archive.vn/yTP0x). However, archive.vn is still proprietary so I installed ArchiveBox which is free software but does not go past the paywall. Does anyone have any solutions?
Option 1 - at least for me WaPo paywalls go away if I disable Javascript on that page. You may want to try that.
Optiom 2 - I find this to be a reasonably well source for archived pages.
