> They're places where people buy a voice and the illusion of support by astroturfing the platform and/or manipulating the algorithm (either through paid advertisements or by owning a platform and controlling the algorithm outright) Anyone willing to take a good-faith stab at why this couldn't equally well be a description of traditional media too - say - the WaPo?
I challenge the notion that they're equal. Social media at least provides vox while traditional media is completely one-way. How much is astroturfing and illusion can be debated forever, but any positive value is greater than zero. Traditional media acts as programming first. Journalistic integrity and trust in institutions has been sold off for shareholder value.
That's an easy way to toss aside a very damaging attack on the public and freedom, with power unlike anything humanity has seen. I'm not sure what "any positive value is greater than zero" means, other than a mathematical tautology, but I certainly don't accept that social media is a net positive.
> Journalistic integrity and trust in institutions has been sold off for shareholder value.
Your reasoning is circular. You both conclude and use as your premise that they've been sold off.
Sadly, after generations of (mostly) not being sold off, of standing up for freedom and professional journalism, in the last couple of months many of the institutions have capitulated.
Part of the cause is you (and people like you): Serious journalism was a threat to the far right, so they did what they always do: Use a campaign of constant repitition and demonization. They do it also to immigrants, trans people, liberals, Democrats, and individuals they see as threats (including any leading Democrats). Part of that campaign is getting everyone repeating it on social media.
Now we have few reliable sources of news left.
