Why Reputable Vendors became thieves ?

Companies which are stealing some another company ideas because the greed of name and fame ! As Microsoft done with i4i in 1996 ! i4i group had launched an XML technology in which you can use XML in your documents , spreadsheets etc !
When the Microsoft market had decreased rapidly they were finding an alternative solution to capture their lost market ! Somehow , Microsoft get access to i4i's patent and copied all the techniques which i4i group was using ! Now i4i markets had an u turn and they lost their market ! Somehow, when i4i claimed that Microsoft are using our logic for XML based documents , the reputable market response of Microsoft was all melt in the dust ! They loses all their fame and reputation in the International market and bears a heavy fine ! 

This is the reason when big companies become thieves and stole all the logics to improve their markets  !

Just in present we have an case of Iphone and Samsung , where iphone had claimed that Samsung had stolen our design which includes keypad design, round corners and home button ! In general for the layout of the smartphone ! Somehow , Samsung won the case !
