Nearly everyone has mocked RBR. We were mocking them even before they released their livery, with the expectation that it would look exactly the same.
Ferrari is Ferrari, slight alterations will occur but no real need to mess with perfection. I liked the shift to more black and less white after the initial departure of Santander a couple years back, because it looked more like the classic Ferraris of the 80s/early 90s. As @Burt Macklin pointed out, The University of Texas doesn't change up its football uniform very much either, because it's already perfect.
Yeah I don't hate the Merc livery, I just commented that it's boring AF. And really disappointing after some of the truly beautiful silver/teal liveries they've rolled out over the past 5 or 7 years.
I DO hate the squashed sidepod look, that's truly, truly ugly. But it doesn't have anything to do with the Merc livery. I understand the technical reasons for deflated sidepods, I just don't like the way it looks. There were technical reasons for the dong-noses a few years back too, but that didn't make them any less ugly.
Now THAT is an example of a beautiful black livery. Tons of graphic detail both subtle and less so. The All Blacks would be proud of that car.
