The tweet in question I'm guessing you're referring to is this:

> I find it distasteful, almost unethical, to say this when you have 18 million subscribers.

> Hard to explain why, but with great reach comes great responsibility. Potentially killing someone else’s nascent project reeks of carelessness.

> First, do no harm.

It's pretty clear they're not referring to JUST the headline/title of the YT video.
