Rumor has it that one of their global's broke and stranded their CEO somewhere remote, and he said get rid of all the bombardier aircraft and replace them with gulfstreams.
If this is true then it has got to be the MOST ridiculous reason for getting rid of one aircraft type for another. And, again, if it's true, all I have to say is "poor baby. Did you miss your favorite TV show because your expensive little toy broke?".
Really? When a company spends close to $50 million on something that is supposed to transport their CEO around with reliability, and it fails to do so, then it should be replaced. It's the same thing as if some vital part in a refinery breaks, and shuts the entire refinery down. Exxon Mobil isn't some private enterprise, a decision like this probably has to go through the board of directors, and CEO's do a little more than watch TV shows.....
