So you have n companies each applying their own subjective judgement over their own networks, or you have 1 government applying its own subjective judgement over all networks in that country.
It's highly unlikely that the latter is more friendly to fringe or extremist views (setting aside whether or not that's a good thing).
Many authors have speculated on how modern society would work if rather than 1 legal system you would have large companies that each have their own laws and enforcement. Usually the world is made into a dystopia.
I think a 1 government is in general more friendly to fringe or extremist people. Not that the laws are better, but government legal system must in its core treat everyone similar where same act done by two people are punished similarly. This aspect of law make people feel safe against arbitrary enforcement and that benefits both people of fringe as well as non-fringe views.
I don't think we can enter science fiction stories into the evidence for this debate. They are fiction.
The events in these books don't even necessarily reflect the beliefs of the authors. An author might simply write what would be entertaining to read, or what has been written in the genre before. Even if these fictional megacorps do reflect the widely held belief of genre authors, that doesn't serve as any kind of factual basis on which to base public policy.
That is true, through we do have historical evidence during the colonial times where large shipping companies were large enough to rival nations and had their own laws and enforcement. Later we also have large mining companies with their own towns, laws and enforcement.
As far as I remember my history, companies that are larger than nation with their own laws and enforcement have not much nice things written about them.
There is potential for an antitrust issue - two companies having immense control over the most popular way to access the internet, your phone. At least for now, it's really more of a convenience thing when app stores remove apps; limiting the feature set of your product offering to apps only may make sense, but it is an educated risk. If you feel you want the most people to access your content, you make it work on mobile and desktop computers without requiring a specific app store gatekeeper.
If you disagree with Apple removing something from an app store, you buy an Android compatible and enable side-loading, or you buy a Linux compatible phone, or if all else fails, you connect through a web site.
When I used Windows Phone, it was annoying that I couldn't download an app for my bank, inconvenient that I still had to use ATMs to deposit checks. And disappointing that I couldn't hop on the Snapchat bandwagon. But I was still able to communicate with friends and family, read the news, do research, learn things, and make use of the internet.
Allowing just a few companies enough control over the internet to take away your ability to choose how you use it is an antitrust issue.

This is empirically false though, at least in the the USA.
In the USA there are extremely strong protections for free speech.
If it was required that platforms followed the existing way that the government is allowed to ban certain speech, then platforms would be much less restrictive, because our laws of what speech is allowed is very pro free speech.
One government is optimistic in this case. This is the EU talking, they'll gladly deliberate for months before any action is taken.
Furthermore, wouldn't this worsen an authoritarian or Trump-like scenario? We are expecting the government to moderate itself? Wouldn't a yes man/crony just sit in that seat ala William Barr and let the tweets go unchecked?
Yeah, in the US, depending on which dystopia you think we're living in, it's very easy to envision either some Trump crony making sure nobody was disrespectful to him on Twitter OR some "deep state" agents starting to censor him way back in 2015 to try to prevent his getting elected in the first place.
I've yet to see a realistic proposal for what should replace Twitter's ability to choose its own TOS that isn't either a worse situation like that, or isn't some "only illegal stuff should be taken down" that probably results in far fewer open places on the internet accepting user-generated content for broadcast in the first place.
It's highly unlikely that the latter is more friendly to fringe or extremist views (setting aside whether or not that's a good thing).
