because maybe some people like to make stuff look differently?
others can’t see the changes, it’s solely user base, not network so its not like you change the way your facebook looks compared to everyone, it’s just rendered differently using code.
and thank god facebook hasn’t turned into myspace! but I’m pretty sure the devs of facebook are going to keep it that way, especially seeing it’s such a huge corporation now. Hopefully they don’t get to power hungry and put up like a billion ads, which oh I will note, stylizer IS good for removing ads.. for pretty much any website.
