Its because theres too many “dead subscriptions”. The algorithm punishes channels that have subs that dont interact with saud channel.

Remember, so long as you stay subscribed to a channel but don’t interact with it in any way(click a vid, comment, dislike it or comments in the comment section) it hurts the channel. Thats why i resubbed to every channel i unsubbed from, that way i can actually hinder them instead of help them. This has been proven from Jesse Cox being told so by youtube staff during meetings he’s had, you literally have to start a fresh channel free from the dead subs to get the algorithm to pick you back up.
