That was true until they started promoting and demoting content in order to drive engagement and juice their ad revenues.
Big tech is not plumbing. The minute Facebook invented the news feed they became editors and content promoters.
If they really want to just be plumbing, they can shut down their algorithms any time.
As an aside, I picked on that part of the post because the rest of it quickly pivots away from tech and reads as a self-promoting, semi-unhinged rant about covid that reads like the drunken ramblings of Q adjacent anarcho-libertarian, complete with the big hits: references to the "Davos elite", hydrochloroquine, ivermectin, Evil Dr. Fauci, etc, etc.
Which reminds me, I should probably flag this post given it's relevance to HN is glancing at best...
