EDIT: I think they delibterately do them that way to be charmingly cheesy, and I mostly appreciate it becuase then I always know when to close the video.
No mention of sponsor, doesn't say "supported by" accept in the top comment that was added later (not at the beginning). The description one wasn't there originally either.
It literally says "because we want you to have nice things, you can get a 30 day free trial". You can't get more deceptive than that.

You are free to not consume content, but automating revenue stripping en-masse from otherwise high quality content is more unethical than the supposed sketchy advertising tactics.
Unfortunately, you don't walk away from this as the moral victor.
In my reddit post complaining about this, people there actually thought this was part of the video and one of the "other things people should be worrying about". This isn't some made up thing, people actually do fall for it.
