I think one of the key differences is something pointed out in the article, in that what the Open AI is doing is a substitute for reading the new york times and possibly a rival to it.

On the other hand having an archive link to a times article in order to discus it is not really a substitute for a times subscription as a news paper has to walk a line of letting some of it's articles be read while requiring payment for others (the times actually allows you to create a "gift link" to do exactly what the archive links do).
