Because the Big-G CEO Sundar Pichai and CFO Ruthless Ruth Porat are merely stewards serving at the wish of and executing orders from, erm, fulfilling the vision of the board of directors (Larry Page, Sergey Brin, etc). At this late stage, it's time to exploit the resources and milk thr asset for every last penny. The board of directors are concerned primarily about profitability and ROI. Nothing lasts forever. Except perhaps man's greedy desire to accumulate ever more wealth and power. This too, shall pass.
