The entire summary, and many people here, are using PowerPoint and presentations interchangeably. So what do they REALLY mean, do they hate PowerPoint itself, the tool, or do they hate the idea of a presentation or slides, a concept used for many decades, or do they hate the person who does a lousy job at making and performing a presentation?
In most of the world, "Powerpoint" is shorthand for presentation software, in the same way that Kleenex is shorthand for facial tissue or Hoover is shorthand for vacuum cleaner. I suspect there are few people who could even tell you the name of Apple's presentation software, let alone any ways in which it is fundamentally different from Microsoft's.
What they really hate is that people making presentations are bad at presentations. But that sounds personal and mean and is a good way to get your target audience to think you're not talking to them, but to some other group of people who don't communicate well.
Second, they hate that powerpoint (or Keynote or Impress) disguises bad presentations in good form. A good presentation has a narrative - a logical flow of ideas - and bullet points are a good shorthand for that flow. Bullet lists can also be a collection of random words. Connection diagrams can be a good way to illustrate the relationships among complex topics, or they can be a disordered collection of random words.
If you're critiquing a presentation (not the slides, but the presentation), and it's a disordered pile of shit, you can ask the presenter to try to identify the main ideas, put them in order, and focus on them. This sounds like "make and follow a bullet-point list," and it's completely useless if the presenter can not distinguish main ideas from details.
Presentation software (Powerpoint, Keynote, Prezi, whatever) allows bad presenters to fill in a lot of shiny graphics and animation. These take up a lot of time, feel like work, and make bad presentations superficially resemble great presentations. The presenter can feel like they've spent tremendous effort making a visual display, which is much easier that organizing their thoughts and content for clear communication. The presenter can look at their slides next to a high-impact, model presentation and see that it contains many of the same elements. The bad presenter is thus able to go through the same motions as the good presenter.
