Frequently, if you paste the link into "archive.is" or "outline.com", you can create (and post!) a link to such content yourself. Outline.com doesn't work for NYT articles, but archive.is currently does: http://archive.is/YamoB

On NYT and many other sites you can bypass the paywall by editing the URL and adding a '.' between the .com and the rest of the URL (nytimes.com./2020/...)
