It's an adversarial game where you (the buyer) want to pay as little as possible, the company (the seller) wants as much as possible, and the SEC (the regulator) is the neutral arbiter of information. Any third party's intention is unknown unless they publish their full portfolio.
I think the analysis by Meritech Capital should win because inside that article, the first sentence already has a direct link to the official SEC S-1 anyway.
For HN audience, it's easier to read the much shorter (even if flawed) Meritech Capital blog post and comment on that -- rather than read then entire S-1 prospectus (~100,000 words!). Those that want to dive into the lengthy S-1 can still do so; the link is conveniently in the first sentence.
This is not the post I upvoted, and I can no longer undo that action. The replacement changed my upvote history to an unwanted version.
I would also disagree with the second part of your statement -- I've never understood why two threads on the same 'topic' is in any way harmful.
Speaking for myself (but probably many others as well)... it's a problem when they both reach the front page of HN.
There's a finite # of slots (30) and I'd rather see 30 different topics rather than 29 because 2 of them are about Procore S-1. And suggesting folks to just click "More" to see page 2 of topics 31-60 doesn't really solve anything because now I only see 59 topics because 2 are dupes rather 60.
When Facebook's Libra got introduced, the front page had ~4 simultaneous threads about it. A few of them thankfully got merged.
