Why does youtube kill the reach of old channels?

The clip-sharing platform has not interfered to reduce distribution to the channel at all; in fact, the crux stems from shifting audience habits, causing products from the past to fall short of meeting today’s demands.

are u referring to channels that are no longer active? i noticed that they reward active channels so you will want to keep posting consistently. its a snowball effect. all the previous videos receive more traffic because of the new videos being posted. also it depends on the relevance of the older videos - have things changed significantly? or is that still accurate?

YouTube isn’t deliberately suppressing the channel’s engagement,The loss of traffic is entirely due to users’ viewing preferences having changed compared to before

It can also be because competition gets stronger.
