Yes, that’s true. The Fediverse is also susceptible to manipulation. That’s why I’m not a fan of broad rules such as “no politics” in the largest communities, as their breadth would make it easy to buy off a few moderators, which shouldn’t be a problem at all if you have even a little capital.
Nevertheless, traditional journalism is dead because its business model is simply no longer financially viable today. Investigative journalism is very expensive and, with the loss of advertising revenue (wnet to search engines and mainstream social media apps), it is simply an impossible business model today. In fact, most of the traditional media today is run at a loss by billionaires like Bezos (Washington Post, among others).
I’m not saying that the Fediverse is a promise of salvation. I’m just saying that it’s the only option left.
The internet as such was originally designed to be decentralized, but it was taken over by big capital, for which we are now being presented with the bill in all the remaining democracies of the world.
In my opinion, the only response can be to do everything possible to return to decentralization, in order to at least put obstacles in the way of the powerful of this world.
Yes, it would be desirable if truth were rewarded and deliberate false information punished. Unfortunately, neither is even remotely realistic:
True, or at least objectively researched, information was the business of journalism, which for the reasons mentioned above now exists only as a farce of itself (but still retains parts of its former reputation as a reliable source of information). I just don’t think there is any way to make journalism work in the age of the Internet (and I’m from Germany where we have publicly funded media).
Criminalizing misinformation would in turn require appropriate legislation. And as is always the case with laws, those in power would use them to make their worldview the only one that is widely disseminated. To see this, one need only look to the US, where the criminal but also wealthy president is already using current legislation to sue anyone who dares to make him look bad.
So, I think the only option that remains, despite all its flaws and problems, is decentralized social media. Of course, it is susceptible to manipulation, but at least it is not directly controlled by those who want to manipulate the discourse in their favor.
It is certainly not a solution in the true sense of the word - in a purely profit-oriented system, there can be no such thing - but in my opinion, it would at least be an improvement on the status quo, in which people like Zuckerberg and Musk can de facto directly control what people perceive as their reality.
