There are a few parts to this. The first is, the future is currently extremely uncertain and therefore short term moves make sense. The second is the same as every other industry, if the price of money (interest rates) is super low people accumulate debt leveraging the future for the present and thereby raising the need for immediate return. This second part creates a feedback loop of constantly needing more and more revenue to pay the lenders. The third part of this is that most megacorps become seriously dysfunctional over time. There are a ton of reasons for this, but it mostly comes down to growing bureaucratization. IBM is among the worst in this regard, and many people predicted exactly this future when IBM bought Red Hat.
