Sorry, I think perhaps to me his writing style came off as amateur at best to me. It seemed rushed, wavering, and made irrelevant arguments without proper build up or context. It wasn't until the very end that he even decided to state the context of mountain view to begin with. Reading it made it sound like over generalizations and frankly just a long reddit rant.
Reading through this article linked here, nothing came off as especially controversial to me. Seeing that the author of the memo seems to have some professional background in the field of biology I would of expected better; at least check for typos.
