You're absolutely right in your blog - Sony did indeed buy in someone else's PDF renderer - that "someone" is Adobe. I think we can safely assume that Adobe know how to write PDF renderers.
The fundamental point is, though, that PDF is a horrible, ghastly, awful, dreadful format for eBooks. It was never intended as an eBook format and it is the worse possible choice. Anyone who "likes" PDF as an eBook format needs to be beaten about the head with a blunt object until they realise this simple truth.
Most PDF files are formatted for US Letter or A4 page size, and it is not Sony's "fault" that there is no good way to display an A4 page on a screen 1/6th the area of A4.
