I'm on board with it too, but the timing and methodology is suspicious. We already got a "protect the kids" law to semi-block TikTok in the US, but it was really about protecting Israel's image (its sponsors even admitted). I hope it's not related to that.
Tiktok in the US previously had an algorithm that wasn't in keeping with US government goals. That's not a value judgement on my part BTW. Personally I avoid the ingestion of opaque algorithmic feeds to the extent possible.
