I agree with the removal of "simply" in most cases, as well as useless flourishes like "painfully simple", but I think the example includes a case that isn't meant to be a rhetorical assertion of simplicity: > really just another way to render a view This is using "just" in the sense of asserting similarity, not simplicity. And in the context of the sentence, it's being set up as the basis for an argument: "(because) X is just Y, therefore we should..." The original document is kind of repetitive and "bloggy", with a lot of reiteration of the same ideas in a way that feels like it's meant to fill in space between code examples. But I don't think this technique of just removing particular words makes it any clearer or better.
