They have every right to delete the puff piece. Saying that the deletion punctures their credibility and posturing significantly more than the article itself. Things will go south in some high-risk venture investments. Owning up to the mistakes at least messages that there is learning. Would be interesting to see other VCs take on this.

I don’t think the parent is arguing for a blockchain one journalism, just that outlets claiming to be “news” should own their mistakes if they want to retain credibility.

I think GGP is conflating "we commissioned an article from an established journalist" with the article being "news". Adtorials, or whatever they're called, have been quite the thing lately and I don't see how this is any different, except inverted.

You’re right, it’s not a news agency, however it is masquerading as one to try and increase their legitimacy. It’s reasonable to criticise their behaviour.
