Beauty has nothing to do with the criticism here. (You seem to have missed, for example, the "and unnecessary" part of the comment; people put in work to make things look this bad.) And "as long as the information is clear" is not a bar that most of the kinds of slides that are under attack can pass. That's in fact the entire point of the criticism.
Somehow other industries outside semi (involving really successful companies filled with technical people who also don't prioritize aesthetics) are able to put together something for people to read by simply... writing shit down (you know: something that actually does involve reading), instead of relying on dodgy PowerPoint slides (that of course don't involve reading so much—but do often involve suffering).

Besides that, the statement that "Semiconductor industry is almost all B2B" is a combination of nonsense (i.e., wrong) and irrelevant. The majority of the semiconductor industry where this kind of material plagues the average worker's day is employee2employer.
