Wall St has deeply and thoroughly captured all of the regulatory agencies charged with overseeing it, as well as most of the powerful organs of government, and thus sits comfortably above the law.
But not above the ire of the media. The media is just as money-corruptible as every other business enterprise and it found a shiny new toy to play with with Uber. There are likely orders of magnitude more workplace culture issues in finance, yet the media has largely moved past lambasting financial firms for that because it doesn't earn them enough eyeballs. Uber is only getting more attention for something many many many businesses are guilty of (and to a far greater degree) because no other company is as lucrative to write about.
