It's only a heist if no one else is as smart as you. If anyone is as smart as you, they would notice that stock buybacks are correlated with a future decrease in price, as the increasing price of the stock is due to manipulation (i.e. the current demand for the stock is not a function of an increase in expected future values, nor does it signal a change in population level discount factors).

This is just your average outrage by people who don't know how to properly reason about financial markets.
