Not what happened to me. Creators I watch who say things that are unfriendly to advertising will just be missing from my literal subscriptions page where my subscribed channels are listed.

Other ones have stopped having their videos appear in my subscriptions page when they drop a new video if I didn't watch previous ones when they released. FD Signifier and a few other channels have correlated this but I can only search for one lane of evidence right now and that's a lot of video to go back through

Here's some trouble shooting guides that were written recently to address this and also other people who correlate this exact behavior verbally affirming or providing screenshots they are on the correct page. There's been at least one plugin made to address the problem, I completely stopped using youtube's frontend because of it. 1 2 3 4

If it hasn't happened to you that's great. Large websites like youtube and reddit don't tend to implement these on everyone all at once. Or you just watch channels that don't trigger the conditions, I have close to 200 that I'm subscribed to so it's a crazy wide sample size. It ultimately correlates with youtube's goals to move people from the subscription page into recommendations so they can be suggested more kinds of videos that are preferred by the company's interests. While I was searching links to post I found that they recently ran a consumer test in may where they removed the subscription page entirely from the app.
