The quotes are for the most part about ideas and creativity being stifled by reading, and this can happen to anyone - it's related to the curse of knowledge and the preservation of the beginner's mind.
Reading others' ideas, especially polished ones with a lot of authority behind them, can act as a filter on one's own (delicate, barely formed) ideas. Ideas already have a difficult path into reality, and others' biases and filters are one major contributor.
I regularly choose not to read on a given subject if I have an idea I want to explore or to clarify my own thinking, and only afterwards do I consult what others have said. Usually I wind up in the same place (or a crude version of that) but sometimes I find a new insight and those are worth it!
