Is there more empty between lines than lines with text?  

Perhaps a reduction in magnification helps to make some text appear, or perhaps the text is "invisible" with some "secret" writing to hide information:
What is that small failed trail at the bottom of the image?
It could also be the lack of support for the versions of the technologies used, a periodic situation in an era of totalitarianism in information technology, but more likely:
The natural and normal ignorance of not being informed about a subject.
