HOWEVER. Writing is its own craft, and requires a totally separate set of skills than your typical engineer-turned-technical-writer is generally equipped with. They tend towards considering only what they want the reader to do or think, not necessarily who the reader might be or what _they_ want to get out of the writing.
The main problems with the "just simply" writing are twofold:
1. The "just simply" words are completely unnecessary filler. Good writing is stripped of superfluous filler words. Writing with lots of filler words is harder to read because scanning, parsing, and then discarding them is additional cognitive overhead. This technology shit is hard enough as it is, save the flowery prose for your poetry.
2. As others have mentioned, the tone of the "just simply" writing comes off as condescending because it implies the author is considerably more knowledgeable than the reader, that the reader doesn't know anything about the topic at hand, and that the reader will somehow reach enlightenment once they are on the same level as the author.
It's not that I am personally offended by "just simply," it's just bad writing, and I won't read that kind of stuff unless I really have to.
