Reddit’s product is ad-supported message boards. It has a high valuation because it gets an incredible number of eyeballs every day and investors want to monetise them. Reddit is flailing because those users aren’t as monetisable as investors hoped. I don’t think it’s a whole lot more complicated than that, not everything has to be a political conspiracy theory.
Twitter is similiar in that you’re self selecting who to follow, and who to engage with. Things you engage with have hashtags, have observable topics and categories that they generally post about, etc. If you’ve ever looked at the categories that you’re in after doing a Twitter data dump, you can see they know a _ton_ about you. What I don’t remember seeing in there is “confidence,” but it might just be that those numbers aren’t surfaced to users, or that it’s encoded in the ordering (and I don’t remember it).
The point is, Twitter and Reddit have largely the same types of signal that Facebook does, but certainly way less than Google. Facebook’s user engagement might be higher, but I’m willing to bet that the number of people using Facebook to follow their friends, and not random businesses and other accounts is greater, thus limiting confidence in understanding about someone’s preferences. What I mean is that my friends might never post about politics, and I might not follow political figures, or other talking heads, that suggest my affiliation…
In Google’s case, they drop a “pixel,” for tracking purposes, on 75% of the web (inflated estimate for effect), and analyze every accessible page on the internet with the goal of understanding what it says. As a result, they have far greater reach in what they can and do know about you…
This thread feels full of vague insinuations that some powerful political lobby is paying to use Reddit to manipulate opinions or something but no actual detail.
