It's a speaker talking about the ethos they'd like to see the hacker community adopt. If you want to call that "pushing an agenda" or "disingenuous" then it would help if you'd clarify what you thought the speaker said they were going to do. They were up front about the fact that they were discussing the values they think are important to adopt – that's exactly what the talk is about!

The talk is a direct response to the "old" hacker ethos. Each point addresses the same topic as the original, so there's a pretty strong relation. It's hard to "abuse the recognition of the original" when you're making a point by point response.

And, those values and approaches the speaker describes in that response are different from the ones in the original. So in comparison to that old version, this is new.

In short, it's completely unclear to me where your criticisms are coming from.
