Given what Glenn Greenwald has to say about The Intercept (who was the co-founder before leaving for similar reasons), and now this -- I think it's entirely appropriate and reasonable that this person wanted to sound the alarm that 'this organization is no longer what it used to be and should not be trusted.'
To pretend like this announcement is like 'every person on the planet voiced their displeasure about something happening' is so incredibly disingenuous.
The Intercept started out with noble goals and intentions, that at least one of it's founders felt have gone so far astray he cut ties very publicly with the company he founded, and now we have another journalist there corroborating his take.
The organization that broke the Snowden Files, along with many other uncomfrotable stories (for those in power anyway) is now a husk of it's former self, and the author is basically telling you if you read closely 'I left because the organization has been coopted and now refuses to run stories that make certain powerful people uncomfortable', and you are hand waving it away as if it's the equivalent to some random twitter using complaining about their coffee this morning.
Glenn Greenwalds statements and actions around The Intercept should have been a wake up call that it cannot be trusted and has likely been co-opted by some Mockingbird-like program, and now we have further validation of the muzzles being put on staff there. If you can't see the forest from the trees here, I don't see how it can't be due to deliberately putting your head in the sand.
