I think demand for legendary armor is high and sustainable enough that the situation may continue pretty much indefinitely. The grind required is huge, and a lot of people are undertaking it with great enthusiasm, and looking at the examples provided by other legendary equipment supports the claim that interest will hang on more or less indefinitely. I'm still constantly running into people who want to do raids to work on that armor or Coalescence, fractals for Ad Infinitum, etc, and those projects have been available for years.
Note that I'm using the word 'may' here because all this is wild speculation about what players will do en masse; it's not a hill I'm going to die on.
You've also got their coverage of the 2016 election, where it's a matter of settled fact that they slept on an FBI investigation of Trump for things we now know actually happened while putting Clinton's emails on the front page at every opportunity.
You've also got them giving a platform to dreck like this - https://www.nytimes.com/2018/01/27/opinion/immigration-stephen-miller.html?partner=rss&emc=rss&smid=tw-nytimes&smtyp=cur - which includes lovely bits like "The foreign-born share of the U.S. population is near a record high, and increased diversity and the distrust it sows have clearly put stresses on our politics."
I'm not one of those people who has accumulated an entire drawer full of examples and is able to provide you with 400 bullet points of what's wrong with the NYT, but maybe two more will help push you to investigate a bit more? The NYT may publish left-leaning content sometimes, but they are not an actual ally of the Democrats, let alone the progressive or far left. They routinely publish Republican lies uncritically, and their perception as left-leaning is one of their best weapons.
