What’s that say about IBM’s relationship with its current customers?
Yeah that sounds odd. I think what they mean to say is that currently the 300mm plant exists primarily to serve IBM's server group. If GF buys the fab there is no way for IBM to ensure that their orders will still be top priority.
That is reality, and there is nothing IBM can do about it if they sell the business. Typical of management-by-spoiled-children, they want it both ways. If they want the cash to do other things, they might as well dump the server business too, or the mainframes, or...
Oh, wait...
