There's something I'm trying to explain to people who come up with conspiracy theories like yours. What you're missing is that there's two entirely difference psychological processes at play and behavioural patterns. The ones you're talking about work the most on the left. They have the left under thumb. Take a look at this:

People on the left all massively consume big news. People call this legacy media. There's an expected process occurring where the internet kills TV, radio and the news paper. The same as TV killed radio or cars killed horse and cart. On the right big news is dead apart from fox and you'll also see big news only has a small share of the over all audience. The right takes their information from many more small and diverse sources than the left. Meanwhile the left primarily takes the news from big agencies that are basically all the same. All adapting the same to the same audience with convergent evolution, all laterally synchronised including a quorum system and are effectively like different breasts on the same single beast. They all sell the same thing but different packaging. Even the talk shows primarily talk about events seen in the same news channels the left is watching.
People on the right are different. It's not a mother - baby relationship with the press. They consider themselves equals and think on even terms. They will challenge what the press is telling them and their own loyalties are often more important than the press's loyalties. You see this now with a massive shift away from Fox news. People on the right still believe in things like the right to think for yourself. You can see they're actually more progressive as they have embraced the internet where as the left is a fully captive audience for traditional established media.
They don't realise that there's basically half the population but mass media be is news media or social media doesn't cater to them. The ultimate result is that there will be a kind of demonopolisation that's naturally occurring though legacy media which now includes traditional monopolies like google will fight against it. You're seeing a natural split toward something like AMD and Intel.
The result of monopolies in things like news media that only caters to half the population gives people on the left a false sense of belonging evenly to the masses when this is not the case. They think they're in the middle when they're shifting well into the far left. Things go completely uncontested on that side. There aren't two sides on each issue. In essence you have a system that treats half the people as if they didn't exist.
The result will be a huge shift away from these platforms. It's an absolutely enormous market. I'm tempted now to pitch in and take advantage.
