RE: making a living
Corporations have to eat too...
so do the self-entitled sociopaths that treat wall street as an ATM
so companies like Microsoft and and Oracle have to screw their hostages err customers as hard as possible. At some point their big customers will realise that they can save wads of cash (even factoring in migration) and walk away - even down here in the colonies i've seen this - they hand over the cash and don't ask questions (of themselves let alone Microsoft et al)
the other aggravating factor esp in the public sector is if the departments don't spend the cash, they get their budgets cut..
