You are making a very different claim here. The parent comment says:
>> The NY Times is pro-union and anti-big-tech [...]
That is the claim. These are the reasons it sues, and my notes on each:
* journalists are unionized and tech platforms disintermediate unions
Thats a broad generalization based on the authors opinion and not necessarily true. The attitude was not reflective of my interactions with journalists either. I would dispute this from personal experience. We can agree/disagree forever, I'm just giving my IRL experience.
* workers that produce articles and create the newsroom culture have a conflict of interest
It could be said that any journalist who covers any subject has a conflict of interest by covering that subject. Thats a bit weak.
* tech threatens the ad revenue of traditional news media.
Yeah. Rising costs of paper also threaten traditional news media. The NYT is profitable and not reliant on ad revenue streams for survival. They have a health revenue stream in number of other areas. In addition, for better or for worse, most journalists don't actually know/care that much about ad revenue given the tradition divides between business and editorial sides (I see that at many media orgs I have worked for - its not just the NYT)
So.. that was what I was talking about ("workers", not a "top-down directive").
In regards to your point: Thats a new and different claim so hard for me to speak to that.
I would note that the claim came from Matthew Yglesias. He since deleted the tweet. I would note that he never worked at the NYT as far as I can tell.
I don't know much of Kelsey Piper, but she "heard it from NYT reporters at the time" so not quite first-hand account either. Her tweet is not a "leak" (thats very different) and I see nothing to prove or substantiate it - just she "heard" it.
I'll keep an open mind but I'm skeptical.
