What exactly is wrong with this? Powerpoint could easily be used for fast notes in a form that likely will be used to present to others in a similar fashion, has online storage with Microsoft 365 subscriptions, pre-made themes and privacy tags that you can set, the list goes on. I wouldn't use it personally, but compared to my usual textedit/notepad file open for fast notes or todo lists, the example powerpoint you told on likely is going to persist longer, be easily accessible by persons without my specific interaction (assuming it gets shared out to "someone"), there are a lot of benefits.

I'm not a fan of powerpoint presentations in any form; I find the medium uninteresting and more of a progress meter for the current meeting than anything else, but even that hasn't been reliable for a long time to know how long a presentation will go, but I don't think using powerpoint in one of the many ways it can be used is anything bad; I'd rather that such hypothetical execs have someone put the notes into powerpoint than write it down on a paper notepad. At the end of the day, all I really care about is that I can read the notes if required and I can quickly access the data without having to bug someone after the initial permissions are set.

(all this being said, I cannot express how frustrating Microsoft Office and Google Office are to me; barring powerpoints where I have no choice but to build it in one of these office suites, I usually just write plain text with markdown formatting and only use office suites to apply the necessary formatting, using the markdown as a reference; I would enjoy word/docs a lot more if there was button to "convert markdown to word formatting", and vice versa)
