I think the core issue here is the elephant in the room in tech that noone wants to talk about. The tech industry has put most of it's money making eggs in the ads basket. This means companies selling ads are promoting the kind of mass information spread that is sensationalist because it gets their ads the most views, and the tech community makes money off of this.
How well do ads actually work? I really don't know. Is there any objective data to measure this? There are three main companies who sell ad spaces on a real time market and it is a very interesting market that I feel like most people know little about, especially people in tech.
Regardless of how well or not well this works, it's what floats companies like Google and Facebook.
I would say the tech companies are the ones fueling this because it is the their multibillion dollar business models that rely on sensationalist news to sell ads. period. To shift the blame to politicians or to even journalists trying to compete with other sensationalist news blogs or companies who make money from selling ads, is shifting the source and the root cause of the issue, from us, the tech community.
To act like as a tech community we are severely concerned about mass information, the spread misinformation etc etc but also not address how we can fundamentally move away from a market in tech that makes money off of anything besides selling ads to people, or selling peoples information to ad companies (and god knows who else, I mean, only the big tech three know who else), is delusional and self serving, at best.
Despite this, I rarely hear anyone in the tech community willing to openly talk about these problems, much less come up with alternative business solutions.
I would love for there to be more conversation around moving away from a tech market that preys on harvesting user data and ads to solutions that solve people's problems instead of activist posturing from people in tech who talk alot about being concerned about politics etc but work for the companies that fuel this spread of misinformation.
