Government already admitted to pointing Facebook to accounts to be deplatformed. Government and social media collusion is now best assumed to be going on. All that matters now is how much the companies are incentivized to push back. The answer: not much.

If this change happened or not due to such collusion is secondary to the thing worth noting: it would not be surprising if it did, it would be consistent with the governments positioning if it did, and it would also be hard to prove if it did, and if it was proven it would be vociferously defended by legions of commentators and the media. All that would need to happen was for the government to suggest the downvotes on pro-vax vids were contributing to deaths and ergo liability, and suggest the whole feature serves as a mechanism for disinformation they may be liable for in general, perhaps criminally so if the feature can be traced back as a proximate cause of something like the capital riot. Poof.
