  Yeah that's a fair point. I’d suggest that’s a reason to think carefully before posting a slide deck, though. If essential points are left off the slides entirely, then it may not be such a good idea to post the slides by themselves.

    I think many people haven't had the issues you personally do with the presentation. That said, other comments in this thread make clear that you are not the only one to have read them as snarky. It's very useful to be charitable and give people the benefit of the doubt when reading their communication. I think there's a lot of useful information in the slide deck presented in a succinct way, and publishing them as-is is a useful and efficient way to do so. I think with very little effort it's easy to interpret the shrugs as I did above, and there's little if any additional information that needs to be address along with the final shrug. I wouldn't have presented it this way, but I don't see any malevolence or negative intent on the part of the author.
