YouTube Premium still has """promotional""" content (read: ads). Ad cards, ad footers, etc.

And your evidence is a screenshot in a reddit post from 2 years ago? Rather than "Open the app and check", which I did, and there a no ads. Nor have I ever seen that promo from the screenshot, or any of those other things you mention.

I'm guessing you are complaining about something that you don't even have?
