Arguably, the post itself is disingenuous because the title includes the Reddit phrase "ELI5" which is "Explain like I'm 5". Folks have pointed out that some of the concerns OP is raising don't hold water (ex. casting a shadow, preventing connection between two areas, etc.). By doing so, these responses are somewhat providing the explanation: setting aside qualitative reasons, there wasn't a clear-cut quantifiable reason to not approve it.

Using "ELI5" in the title seems like a way to get people commenting with the assumption it would be an informational thread exploring the reasons for and against the building, but...well, you've seen how this thread has played out.
