I never understood this reasoning. Prior to X being purchased by Musk, every major social media platform had pretty much exactly the same speech policy. You'd see decisions made in unison.

For instance, this was the timeline for Trump being banned off social media

January 6-7, 2021: Facebook and Instagram initially suspended Trump's accounts for 24 hours, then extended it "indefinitely"

January 7, 2021: Twitch disabled Trump's channel

January 8, 2021: Twitter permanently suspended Trump's @realDonaldTrump acc ount

January 9, 2021: Several other platforms took action, including:

Reddit banned the "r/DonaldTrump" subreddit

Shopify removed Trump-related online stores

Snapchat disabled Trump's account

Various dates: Other platforms like YouTube, TikTok, Pinterest, and others implemented their own restrictions or bans around this time

Obviously this banning didn't occur due to actions on their platforms, but an organized effort was made to remove a person's digital presence from the internet. And it more or less worked for a long time.

Is a social media monoculture really a good thing? Nearly every other platform has pretty much the same policy on whatever the Mastodon CEO thinks is 'hate speech'.
