Every crowdsourced news aggregation site faces the same challenge, too. Digg had serious vote manipulation problems. Reddit's /r/politics section was overrun by pro-Clinton activists, etc. Concerted, concentrated effort can almost always overpower the consensus of average users.
EDIT: to be clear, my point is that if/when this becomes a powerful tool, the incentive to aim it at a broader or different set of goals is overwhelming.
This is the same basic difference that you can see between good and bad science lectures in schools. Bad lectures give students a bunch of formulas they have to trust and memorize. Good lectures describe how the world works, which they can confirm through their own observations and experiments.
Anything that relies on blind trust in some curator will eventually have the exact same problems news most media has right now.
If its not news sites, its images with some text over them, videos, etc.
[1] propaganda, noun, derogatory: information, especially of a biased or misleading nature, used to promote or publicize a particular political cause or point of view.
His comment is claiming that fake political news should be distinguished from the fake tabloid style news (bigfoot sightings/alien abduction/etc. that we've become accustomed to in the grocery store checkout aisle). The former is propaganda, the latter is not.
This distinction is correct, in terms of everyday usage of the word.
Your claim that "everything is propaganda" is plainly false. An author having a political agenda is not sufficient to render an article propaganda. This would be similar to claiming that every article written by someone with sexual desire is "pornography." It's plainly ridiculous, unless you are operationally defining "pornography" to mean something other than it does in everyday written English.
Things that are propaganda:
1. fake news stories disseminated with the express intent of influencing elections, which are known to be false by the author of the article / editor of the publication / etc.
Things that are not propaganda:
1. stories about bat children in supermarket tabloids
2. your comments
Things that might be propaganda:
1. fake news stories about political figures that appear in tabloids that also produce bat-child news (the article is false, the article might publicize and promote a political cause, but it isn't clear that it is a tool deliberately crafted to do that). What would clearly be propaganda in this situation though, would be a liberal/conservative/etc. spin site republishing a fake tabloid news story about Clinton/Trump that they must in good faith know is false).
That statement isn't untrue, it is objectively observation with one's eyes or using spectrometers in the case of an individual who is colorblind. It isn't binary, statements can be rated on a range of truthfulness from false propaganda to very objective...and, arguments that are isomorphisms of "all sides do it" are harmful because they essentially justify parties who benefit from such propaganda.
"The sky is blue" is a non-political statement only because no one stands to make money convincing people otherwise.
"sky is blue" < "here's a snowball"
< "avg temperature of Earth's surface is rising"
~ "${average_comment_on_HN}"
<< "This snowball demonstrates climate change is a hoax"
< "${fake_news_articles}"
Is is fair to put "${random_comments_on_HN}" in the same category as "${fake_news_articles}" because they are both "propaganda?" No.The problems that face us will not be solved by siloing ourselves away from views we disagree with. It might take more effort to filter out bullshit in our current age, but if we're not even aware of the bullshit someone else is feeding off, how are we going to combat it? We need to bring more people into public debate, not isolate them.
Also, confidence in the press is at an all time low, so there is already awareness. [1]
