It is not that you got discriminated. They use different algorithms plus Google has recently updated their core algorithm by combining it with Panda (the On-Page algorithm).  This has caused a lot of fluxuations last month and I am still seeing some movement.  I would focus on ranking on Google based on the fact that they have approximately 80% of the Search Engine Market share.
