I really feel for Danny Ricciardo, it was great to see him up there on the podium, but I feel that his team let him down. The disqualification was entirely justified and it is very unlikely to be overturned. All the teams were using the same sensor and several of them weren't happy with it. Basically Red Bull told the FIA to go jump, whilst the other teams turned down their fuel flow as requested. Therefore, it wasn't a level playing field. There's a good article on Autosport.
no other team went down the Red Bull route and deliberately ignored the sensor reading
