What Sony did to Sega isn't the same as what Microsoft is doing to Sony. Sony pushed Sega out of the console race because they did a good job of telling people not to buy a Dreamcast and buy a PS2 instead. Which at the time is quite remarkable because all Sony had was SSX while Sega had dozens of great titles. In my opinion is was karma on Sega's part after they openly attacked the PS1 in commercials for the Saturn.
