Some of these are, as others have commented, guidelines meant to be broken. Others are solid insights into technical limitations leveling the playing field (Phase One being equal to a phone after compression and resizing when displayed on a phone).

I have to say that the one regarding the rule of thirds was... wrong. Thats always been a rule to break, and square isn't even close to a new format. Shooting 120 film in 6x6 is, and was, common. Its what the Apollo Astronauts took with them. Its also my favorite format.
