I'm not sure how much time you've spent on using YouTube and I'm in no way a big fan of YouTube, but please do not be too hard on yourself on wishing your time back.
As for me, I'm still using YouTube via NewPipe as well, being subscribed to about 8 channels or so, which upload on average once per week. For me watching these videos is relaxing and as long as you don't spend too much time using it and as long as it does not get in the way of more important things in your life, you shouldn't be too hard on yourself on having wasted time. Humans simply need some time to relax and you can't expect yourself to be productive as long as you're awake.
Nevertheless, I'd wish that the content creators I followed were on other platforms, preferable libre and not controlled by a giant company, such as PeerTube, but sadly there aren't any monetary or other incentives for them to do so.
