There's a legitimate debate to be had over the consequences of the 1994 crime bill and whether or not is was a good policy. The point is that Instagram (and every other social media platform that puts these disclaimers on their posts) is not merely moderating content any more. They're actively participating in politics and trying to persuade their users to feel a certain way about controversial topics. Which is to say, they're really no different than Parler or any of the big box media outlets.
