Let's also be honest: most of us who follow and comment on HN aren't the average Joe.
Most of us have a STEM background, a critical spirit forged by scientific method, we usually don't forge an opinion after reading a single source, and most of us know how to (at least roughly) estimate the trustworthiness of online content, based on simple factors - how clickbait is the title? what sources are cited? how many ads and invites to join Telegram channels are on the page? how is the weight balanced between facts and opinions?
So some of us may rightfully feel insulted when tech players like DDG decide to take down disinformation or rank it down. We don't like being babysitted, we feel that we're smart enough to read content from multiple sources and apply our discernment to come up with a reasonable synthesis. We don't like it when somebody puts the garbage out of our sight, because we may be curious to investigate that garbage.
The average Joe out there, however, doesn't have such skills. The average Joe isn't yet used to the bombardment of information of the 21st century. The average Joe still reads a headline without reading the content, because they went within a couple of years from following 1-2 news channels to being bombarded by algorithmic-curated infinite timelines and search results, and they don't know how to process it all. And, if the headline resonates enough with his/her biases, they reshare it blindly. The average Joe won't collect data from Statista to figure out how economic and political metrics shape events. The average Joe wants somebody who does the synthesis work for them and distills information into a headline that they can easily grab. I know this well because it's what most of my family contacts do.
And disinformation players know this quite well. They have figured out how ranking algorithms work, they know how to craft content in a way that it gets viral, and they know the SEO rudiments well enough to push it up in the search results.
So keep in mind that such measures aren't taken for people like us, but for the majority of people out there that are much more vulnerable than us to disinformation and to its psychological tricks. When I look at things from this perspective, I am grateful for tech players who take actions like these. After all, if I want to dig enough I can still find the "Russian perspective", and I can still analyze it and/or debunk it. But I'm happy that the average Joe doesn't have to be exposed to this sh*t anymore.
The only downside of such measures is the usual one when you implement any form of arbitrary information filtering/ranking: disinformation won't go away, it'll just go deeper underground, where it's harder to monitor. This is already the case: lots of false beliefs held by my family and acquaintances don't come from content published on websites, but content shared on Telegram groups (often involving deep fake videos, snippets from movies and music videos repackaged as memes about real war events, videos of Putin speeches with completely wrong subtitles, and so on). It's easier for a fact checker to monitor disinformation openly published on the web rather than on a myriad of chat groups. And I don't think that anybody has a solution for this problem yet.
