For me, credibility isn't binary, but a spectrum. I saw problems before (NYT was never one of my heroes, per se, but just a high-quality, thoughtful, high-integrity newspaper). It always had its flaws, but for the most part, it seemed okay pre-Trump. Especially during the Trump years, but a little before as well, it seemed like the ends (on both sides of the increasingly polarized political spectrum) became more important than the means, and a lot of formerly credible institutions moved into a post-truth era.
Sadly, the NYT was one of the victims. So was a big segment of academia.
The American civic discourse feels disingenuous and hollow in a way it's never felt before in my life.
