As much as it sucks for the 2000 people who won't have their offers honored and especially who many have left other roles for the chance to work at Google, this is the devil's bargin of contract work. You are there specifically so the company can adjust labor resources in real time and with minimal consequences or press. If you don't want to be treated as extra-disposable and second class then don't take contacts, because they are higher risk than FTE.
Of course you will also be cutting yourself off from opportunities to quickly gain new experiences, and contracts can frequently lead to FTE offers if your agency structures their contract in your favor.
