Presumably every user appreciates the anti-spam filtering these sites do, and anti-scam/phishing, but there should be a separate checkbox (ticked by default) for "Remove misinformation about covid/vaccines", and one for "Remove misinformation claiming the election was stolen", etc.

Then the social media companies can say to governments "If you would like all users in your jurisdiction to be unable to opt out from these categories, please pass a law requiring us to hardcode these settings for them, and we'll update our UIs to tell users why they can't opt out."

Better yet, the social media companies should say to governments "Please provide your own list of which posts are misinformation, and we'll make sure that users see a blank page saying 'Your government has deemed this post to be misinformation' instead of the content they want".
