People choose to use push models for content through meta properties, tiktok, and aggregators like reddit and HN, but nothing is forcing them to. If they push enough bad content, people won't keep using them. Already happened with Facebook and Reddit predecessors, probably happening to Reddit now.
It doesn't matter how big the haystack is when you have the ability to go directly to the needle.
