For what it's worth, my opinion is that there was no a better platform than social media to host that material.
The media companies are virtually all editorially aligned with one side, and they put their thumbs on the scale when it comes to the news about this subject.
The mainstream reporting is so clinically sanitized that it loses all potency and the sense of urgency. They were never going to be conduits for this material.
The best platform is the one that allows you to reach a wide audience so the onus is on them to archive, not on the vulnerable people being hunted with impunity.
