You can't share the font software with your audience, and since the only good way to share a slide deck with an audience is PDF (otherwise you'd literally have to share the font itself alongside the deck), and PDF embeds the font, you can't share a basic PDF either.

So, couple things:

(a) You can just not share the deck at all. That's my strategy. Slide decks suck. Sharing them also dilutes the value of your talk; a single talk can be given more than once, as long as you don't publish it.

(b) You can ignore the license. Many other people do that. You are unlikely to get burned by the H&FJ police for doing that. One imagines H&FJ is much more concerns about agencies and big companies accidentally publishing their whole font library in their professional PDFs.

(c) You can, instead of designing your talk in Keynote, design it in Illustrator (bonus: Illustrator is way better), slice the slides up on artboards, convert the type into outlines (a 1-click operation in AI), export them to individual PDFs, pull them into Keynote, and share that.
