Yes, it has, to a degree. C.f. Alex Jones, Milo Yiannopoulos, etc. (These voices became much less prominent after their deplatforming.) There's also a deontological argument to be made for banning dangerous falsehoods on one's platform.
The problem was giving him access to a much broader public, to sow paranoia and FUD among tens or hundreds of millions of people who actually play important roles in society and don't have time to spend debunking everything they hear.
Also consider that he's lost a lot of his ability to grow his audience, which is no small thing.
Banning on platforms for whatever reason reduces the platforms reach and raises the platform the party moves too.
We use to separate people by race now we do it by idea. Now sure martin luther king or lennon would agree.
That's very different than the government (not a private company) trying to shut you down from speaking anywhere.
That's dishonest? What's dishonest is you misreading my comment and then blaming me for it.
January 8th - China identifies new virus causing phenomnia-like illness [1]
January 10th - China reports first death from new virus [2]
January 21st - The outbreak, which began in December in a seafood and poultry market in Wuhan, a city of 11 million, is spreading: Patients have been identified in Beijing, Shanghai and Shenzhen, as well as Taiwan, Japan, Thailand and South Korea. [3]
Don't blame our inability to react to the virus on China. The pandemic was raging for months, with news coverage of people being locked in their own apartments, doctors dying, makeshift hospitals getting set up in stadiums, before it exceeded more than a handful of cases in the West.
Hell, even after hundreds of thousands dead, we still don't have the political will to do what would have been necessary to stamp it out back in March - massive testing, massive contact tracing, enforced quarantine. If we were to go back in time, and do it again, I think we would arrive at pretty much the same outcome.
The 'China hid the facts' [4] narrative has little explanatory power, and its primary purpose is to shift the blame from our own failings.

[4] It[5] did hide the facts, but it hid them so poorly that everyone who was paying any attention, both inside, and outside China was aware of how serious this pandemic is at the start of the year. It's hard to hide the facts about something when you put an entire city under lockdown (But don't cut the telephone and internet lines into it.)
[5] China isn't a monolith. To be exact, local government did its best to downplay the pandemic. National government was not very happy with how that went down, and purged their local and regional party branches for their mishandling of the outbreak.
I'm sure we can trust our censors to never do something like that! They have our best interests at heart, right? Nothing like this could ever go wrong, there's no examples from history or fiction about anything like that. Nope, it's always Wonderful Good People that only ban things that Bad Evil People would like, and reality is totally black-and-white, and only Bad Evil People would think otherwise.
If Alex moves to another platform wouldn't part of his following move to this platform? Wouldn't that grow others in that new platform.
Isn't deplatforming just replatforming. With every deplatform doesn't it leak more users to the new platform.
If they deplatform them one day it could be you.
Please don't put words in my mouth. I said I did not need "perfect evidence." I cited evidence, albeit imperfect. Whether it's strong enough to change someone's beliefs is between them and their epistemology. That's all I have to say on this subject.
But you need one to change hearts and minds.
