I am still a Post subscriber, and I wasn't bothered by them removing the Harris endorsement. I personally don't like the idea that a paper should be endorsing ANY candidate. It just feels very "we know better than you, listen to us" which is against the spirit of the press, in my opinion.
I definitely would've had a bigger issue had Bezos forced them to endorse Trump (partly because I don't like the idea of endorsements, and I wouldn't have agreed with their endorsement, but most importantly that the owner is now tipping the scales).
But in this case, the result was a neutral one (they didn't endorse anyone), isn't that what we want from our newspapers? To be neutral during elections and just report what's going on?
